摘要： An armature composed of a shaft and an armature core is rotatably supported in a housing of a rotary electric machine. The shaft is forcibly inserted into a center hole of the armature core formed by laminating core sheets. Each core sheet has a center hole and outer holes connected to the center hole. A contour of the center hole is not continuous because the outer holes are connected thereto. The shaft can be firmly connected to the laminated core sheets with a relatively low inserting force. The shaft has a smooth outer surface having no knurls or the like. In addition, the outer holes of the laminated core sheets form cooling air passages in the armature core in its axial direction.

摘要： An electromagnetic switch includes a contact holding member connected to a plunger in order to hold a first movable contact. The contact holding member is disposed outside a switch case covering a periphery of an excitation coil. A return spring pushes the plunger back in the opposite direction to a fixed iron core through the contact holding member when electric power supply to the excitation coil is stopped. The return spring is disposed outside the switch case. In this structure, a spring holding portion does not need to be disposed in the fixed iron core and the plunger. Therefore, an area where the fixed iron core attracts the plunger can be increased, so that an attraction force can be increased.

摘要： In a rotor of a rotary electric machine, a rotor core is formed by helically winding a material sheet. The material sheet forms teeth on a first side of a middle connecting portion and projections projecting from a second side of the connecting portion in a direction opposite to the teeth. The material sheet is one of a pair of material sheets formed in a single base sheet in a form of belt. In the base sheet, the material sheets are arranged such that the projections are intermeshed with each other. The material sheet is helically wound such that the projections are located at an inner diameter side of the rotor core.

摘要： A pinion gear of a starter is engaged with a ring gear of an internal combustion engine by restricting rotation of the pinion gear while driving a motor at a low speed. After the engagement is established, the motor is driven at a full speed by supplying a full current, thereby cranking up the engine. A crank bar for transferring movement of a plunger in a magnetic switch to a pinion-rotation-restricting member is divided into two or three portions. After the divided portions are assembled to the starter, they are connected together to form a solid piece. In this manner, a process of assembling the crank bar into the starter is simplified.

摘要： In a starter, when a magnet switch is operated for starter operation, an auxiliary movable contact connected to a main movable contact by a holding member comes into contact with an auxiliary stationary contact to supply an electric current from a battery through resistors, auxiliary stationary contact and auxiliary movable contact to apply a low voltage to a motor for low speed rotation. Subsequently, as a plunger of the magnet switch moves further, the main movable contact comes into electrical contact with a main stationary contact, so that the resistors are short-circuited and the electric current from the battery flows to the motor without flowing through the resistors to drive the motor for high speed rotation.

摘要： In a starter with a planetary gear speed reduction mechanism, a first output shaft retaining member (retaining member 10, washer 20) and a second output shaft retaining member (pinion retaining ring 250) are mounted on an output shaft 220 in such a manner as to sandwich from axially front and rear directions a bearing support portion of a housing 400 which supports one end of the output shaft 220, so that a thrust load in the frontward and rearward directions of the output shaft 220 is received at the front and rear end faces of the bearing support portion of the housing 400. Therefore, the axially rearward movement of the output shaft 220 is regulated assuredly without regulating it by the rear end face of the center bracket 360 and the mortor partition wall 800, thereby preventing deformation of the center bracket.

摘要： Around the outer circumference of an armature core 520, there are arranged a stator core 558 and a stator coil 559 wound on the stator core 558, forming a fixed magnetic field device. The stator coil 559 has its one end portion arranged in the space at the outer circumference of a planetary gear speed reduction mechanism 300, i.e., at the outer circumference of a center bracket 360. A motor partition 800 is formed with a stepped portion 810 so as to accommodate the aforementioned one end portion. On the other hand, the other end of the stator coil 559 is arranged in the space at the outer circumference of a brush 910. In short, the planetary gear speed reduction mechanism 300 has its external diameter made smaller than the inner circumferential diameter of the stator coil 559.

摘要： A starter having a highly reliable overrunning clutch which has grooves on both a clutch member inner and a clutch outer member. Rollers are sandwiched from the front and rear torque conveyance direction by the roller contact surface of each groove, so a large stress such as with the roller-type overrunning clutch using the wedge-effect is not applied on each contact surface and roller contact surface. This reduces the inertia of the clutch, and suppresses the impact force generated when a pinion engages an engine ring gear.
