摘要： A magnet switch includes a resinous switch cover and an external terminal. The switch cover has a cylindrical metal member insert-molded into a fixing portion, and the external terminal is disposed inside the metal member. The external terminal has an anchoring head having a first sealing surface at one end and a screw portion extending to the other end that protrudes from the switch cover. A nut is screwed to the screw portion at the other end so as to generate an axial force between the nut and the anchoring head, thereby fixing the external terminal. The switch cover has a second sealing surface opposite the first sealing portion, and a seal member is disposed in a gap between the first and second sealing surfaces to seal the gap.

摘要： In an electromagnetic switch of a starter, a bobbin has two terminal holders on a flange. Each of the terminal holders defines a slot on its end surface and a terminal is press-fitted in the slot in an axial direction of the bobbin. An end of an excitation coil wound around the bobbin is pulled out the bobbin and connected to the terminal. A molded cover provides a through hole and is mounted on the terminal so that the terminal passes through the through hole. A sealing member is press-fitted on the terminal to air-tightly seal the through hole. A rod cover fitted on a rod supporting a movable contact has slits on its cylindrical part in the axial direction. The slits are closed before a distal end of the cylindrical part.

摘要： A shock absorber for a starter is presented. The shock absorber includes a rotary disk, a stationary disk and a disk spring. The rotary disk is pressed by the disk spring against a stationary disk to generate frictional force when the rotary disk is rotated by an excessive shock thereby absorbing the shock. The rotary disk has a plurality of press-formed rectangular dimples at a surface opposite the stationary disk, and each side of each the rectangular dimple inclines to a direction of rolling of the raw material of the rotary disk.

摘要： In a multilayer brush composed chiefly of copper and graphite and incorporated therein with a solid lubricant, which consists essentially of two types of brushes, a high-copper-content part brush containing the copper in a large quantity and a low-copper-content part brush containing the copper in a small quantity, at least the high-copper-content part brush contains zinc in an amount of from 0.1% by weight to 5% by weight, and the zinc and the copper form an alloy. This can provide a multilayer brush having a superior durability, which can prevent the performance of motors from lowering, without use of the harmful substance such as lead, and may less undergo any wear due to mechanical and electrical sparkling of the brush.

摘要： In a rotary electric machine, a collar for restricting expansion of coil ends includes a boss fitted on an armature rotation shaft, a flange radially extending from the boss and a pressing portion for pressing coil ends toward an armature core. The thickness of the boss is greater than that of the flange, so that the force F1 that is caused by deflection of the flange when coil ends expand due to a temperature increase is smaller than the force F2 that is required to remove the boss from the rotation shaft. The force F1 is applied to the boss in a direction that the collar separates from the armature core. Because the pressing portion presses against the coil ends toward the armature core through an insulation ring, the coil ends are restricted from expanding by a centrifugal force when the armature rotates.

摘要： A starter motor includes an intermediate gear engaging with and driven by a pinion connected to an output shaft of an electrical motor. The intermediate gear is coupled to the pinion by means of a retainer to be shifted in its axial direction together with the pinion. The intermediate gear engages with a ring gear of an engine to crank up the engine when it is shifted in the axial direction. The retainer is connected to a pinion boss by forcibly enlarging a resilient opening of its groove, and the resilient opening recovers its original position after the retainer is connected to the pinion boss. In this manner, the retainer is prevented from dropping off from the pinion boss during an assembling process of the starter motor. The retainer is made of resin to have an enough thickness to secure a sufficient mechanical strength.

摘要： A brush holding device of an "easy-to-assemble" type disposed between a yoke and an end frame of a motor. The device has a brush holder formed in one body from an electrically insulating material to include an annular-type field winding fixing frame, a brush holding stay having a plurality of brush chambers thereon, each of the brush chambers having at least an opening on the side of the end frame, integral connecting portions annularly connecting the spaced brush chambers therebetween, an insulating plate member having relatively rigid body portions to cover the openings of the brush chambers and relatively flexible portions connecting the body portions therebetween, and means for fixing the insulation to the brush holders by deforming the flexible portions of the insulator toward the brush holders. The aforementioned annular fixing frame has a plurality of flanges radially outwardly extending from the outer periphery thereof by which the annular frame is circumferentially axially aligned with the yoke. Consequently, the brush holding device is able to be rigidly held between the yoke and the end frame without using a bolt while establishing a good alignment of the device in the circumferential and the axial direction.
