Electric equipment is provided for mounting on vehicles and electrical machines having superior rust-prevention film, which makes it possible to prevent vehicles from generating red rust even if outer surface of magnetic core housing of the vehicle is damaged by bouncing a stone and the like during running, and also to provide manufacturing methods of the same. Any outer surface and surface exposed outward of the magnetic core housing is coated sequentially with a metal plated layer or an alkali zinc plated layer, chromate film or zinc phosphate film, and organic resin coating.

In connection with an intermediate anchoring of a manipulation cable connecting between a manipulation side and an actuation side of an automobile transmission mechanism, an intermediate anchoring bracket 22 of the manipulation cable 4 is provide integral with the starter 2. Specifically, a front bracket 21 of the starter 2, which is attached to a transmission block 1 with a high positional accuracy according to an original purpose of improving engagement between a ring gear 32 and a pinion 23, and the anchoring bracket 22 defining the intermediate anchoring point position of the manipulation cable 4 are formed integral. By merely attaching the starter 2 to the transmission mechanism block 1 with a small number of parts, an accurate positioning of the anchoring bracket 22 with respect to an actuation point 1a is realized, thereby, a positional accuracy between the intermediate anchoring point position and the actuation point 1a can be improved.

A starter motor has a rotating armature with a rotating shaft on which a groove is formed, a rear bracket, and a cylindrical-shape yoke connected to a front bracket which supports a pinion shaft. A holder washer member is inserted rotatively in the groove and limits movement in the axial direction of the rotating armature. A holder plate member is provided with a brush holder member. The holder washer member is sandwiched in an axial direction between a step portion of the rear bracket and an inner peripheral portion of the holder plate member. An outer peripheral edge portion of the holder plate member is sandwiched between an outer peripheral edge portion of the rear bracket and a step portion of the yoke. As a result, the rear bracket is fixed by a through-bolt to the front bracket. In the starter motor structure the holder plate member can be fixed to the rear bracket without using a fixing component such as a screw.

A plurality of insulator-coated coils wound in slots of a magnetic core in multiple layers have end portions including at least contact portions without insulator coatings and connected to risers of a commutator, and adjacent portions next to the contact portions but out of the risers. A stepped portion is formed in at least one of the adjacent portion of an upper coil and the adjacent portion of a lower coil of the insulator-coated coils wound in multiple layers at a location where the upper coil and the lower coil face each other in crossing relation. A sufficient gap distance between the upper and lower coils is ensured at the location where the coils cross each other, and the productivity of revolving armatures is improved.

Between the first pulley 22 fitted on the output shaft of the direct current motor 20 for driving the internal combustion engine 100 and the second pulley 11 fitted on the crankshaft of the internal combustion engine, the belt 40, which is power transmission means to transmit the driving power of the direct current motor to the crankshaft of the internal combustion engine, is installed. Between the output shaft 21 of the direct current motor and the first pulley 22, the lift off type one-way cam clutch 23, wherein the cam lifts off by the centrifugal force causing release of the power transmission engagement between the inner element and the outer element, is provided.

In a permanent magnet field starter motor, a ring shaped enlarged portion is formed at an end of a yoke and has an inner diameter Da which is larger than an inner diameter of the yoke. The inner diameter Da of the enlarged portion is at least as large as an outer diameter Db of a brush member holder plate which is inserted to an inner side of the enlarged portion, so that the radial position between the yoke and the brush member holder plate is directly aligned. A cut-out groove is formed on the yoke for inserting a bush member. The bush member is inserted into the cut-out groove, so that a thrust direction position of an outside portion lead wire, a lead terminal, and a lead wire is determined. A projection formed on the brush member holder plate has a width Wb which is at least as large as the width Wa of the cut-out groove. By inserting projection into the cut-out groove, the circumferential position between the yoke and the brush member holder plate is aligned.

In a starter, durability of a pinion and a ring gear is to be improved by eliminating such as a collision by bringing them in mesh with each other. A rotatable intermediate shaft (for example, an input shaft of a generator) is interposed between an output shaft of a starter motor and a crankshaft, a ring gear is mounted on this intermediate shaft via a bearing, the ring gear and a pinion are normally brought in mesh with each other. A movable clutch element for coupling and releasing of the coupling between the intermediate shaft and the ring gear is fitted by a spline to the intermediate shaft, and a stationary clutch element is provided on the ring gear. When a starting switch 1 is turned ON, the clutch element is moved on a side of the ring gear by means of a lever and when the starting switch is turned OFF, the clutch element is separated from the ring gear. The intermediate shaft and the crankshaft are coupled with each other via pulleys and a belt.

A starter for an internal combustion engine including mechanical components subject to an impact load during operation including a shift lever, internal gear, gear cover formed integrally with the internal gear, front case, center bracket, and brush holder disposed in a rear bracket. At least one of the mechanical components is formed of a synthetic resin having a glass transition temperature greater than 90.degree. C. such as an aromatic copolymer and nylon series, whereby a workability and an impact load absorbing capacity of the mechanical components as well as the bending rupture strength are capable of withstanding an impact load caused by an abnormal operation of the starter at a high environmental temperature greater than 150.degree. C.

A rotor is fitted on a rotational driving shaft of an internal combustion engine. Permanent magnets are arranged on the circumference of the rotor. Opposing the permanent magnets, a number of coils for charging a battery used for lighting, and a group of coils for charging a condenser used for ignition, are arranged on the stator core radially. The group of coils for charging the condenser are arranged on a number of salient poles extending along the axial direction of the stator. The coils for charging the ignition condenser generate two separate voltages at low and high rotational speeds of the engine.

Between a relay terminal of a direct current motor and a contact terminal of an electromagnetic switch, there is provided a fuse which is melted to cut off an electric current upon reaching a predetermined temperature. By properly setting the predetermined temperature at which the fuse melts, it is possible to make the fuse heated to a high temperature and melted in a relatively short time to cut off the electric current in the event of, for example, a continuous operative condition caused due to such a failure as fusion adhesion of a movable contact point with a B-terminal and an M-terminal or fusion adhesion of a contact point mechanism outside a starter, or an overcurrent supply condition caused upon a rotor being locked.
