摘要： PURPOSE:To improve assembling work and workability and enhance the effi ciency of motor by installing a bracket which closes a yoke opening and includes a bearing portion supporting an armature shaft and by directly fixing the bracket to a brush holder. CONSTITUTION:A disk-shaped bracket 5 is attached to the opening part of a yoke 2 consisting of a cylindrical magnetic member; and bar ring process portions 33 with the same number as that of brush holders 4 are attached to the bracket 5 and arranged almost on a concentric circle with the rotating shaft of an armature shaft 13 at the center. Also, the bracket 5 formed separately from the yoke 2 and including the bearing portion 6 supporting the armature shaft 13 and the brush holders 4 are directly fixed by single fixing means. Therefore, the positional accuracy of a brush 52 slidingly supported in the brush holder 4 and a field magnetic pole can be improved. By doing this way, assembling work and workability can be improved and the motor efficiency can be enhanced.

摘要： PURPOSE:To make a turning angle of a hole helical spline at time of assembly automatically determinable by installing a rotational moving engaged part of the hole helical spline in a recess part of an output shaft. CONSTITUTION:When a preassembled pinion mechanism is inserted in from the right of a tip of an output shaft 2, a spline tube 5 is reached to a helical spline 2B, further passing through a root part of a rotational engaged part, and an edge of the spline tube 5 hits on a second axial engaged part 2D, thus its axial movement comes to a stop. At this time, spline engagement comes off, and thereby a hole helical spline 5A is made rotatable. Then, when this hole helical spline 5A is rotated, it hits on a rotational engaged part 2C and its rotation is stopped. This turning angle is equivalent to one crest portion of the spline, and when this hole helical spline 5A is put back to the original place in this state, spline engagement takes place again, and when it is further restored, its edge hits on a first axial engaged part 2A, so that it comes to a position at time of maximum movement of the pinion mechanism.

摘要： PURPOSE:To downsize the motor section by employing a step structure in which the inner diameter of yoke at a part corresponding to a holder plate system including a brush is set larger than the inner diameter of yoke constituting the motor profile. CONSTITUTION:Stator of motor 44 comprises a yoke 43 and a field pole 51. The yoke 43 is constituted such that the inner diameter at the brush fixing side end 43b and the reduction gear fixing side end 43c is larger than that at the field pole fixing section 43d. When the inner diameter of the yoke 43 constituting the profile of the motor 44 is extended as required to provide an axially stepped structure, the field pole fixing section 43d of the motor 44, i.e., the yoke 43, can be downsized. Furthermore, since the brush 62 is ensured to be longer than a predetermined length it can be freely regulated in length according to the durability of the motor 44, resulting in enhancement of reliability. At the same time, only the motor 44 can be downsized except such parts as reduction gear system 13 which is difficult to downsize in view point of strength.

摘要： PURPOSE:To restrain the rise in the surface pressure between a planetary gear and an internal gear, and to prevent the deformation of the internal gear by constituting a reduction starter in such a way that the impact torque applied to the internal gear can be absorbed by the circumferential relative elastic deformation via a flange between the internal gear and a ring-shaped cushioning part fitted thereto. CONSTITUTION:A planetary gear reduction mechanism 3 incorporated in a motor bracket 1 between a motor housing 2 and a front bracket is made up of a sun gear 4, three planetary gears 5, and an internal gear 6, and the sun gear 4 is formed at the end of the motor shaft 7 of a starter, and the planetary gears 5 are journaled by the flange part 6a integrally provided at the rear end of a starter output shaft 8. And the internal gear 6 is provided to the flange 9 with a boss 9a that has been fitted on the outer circumference of the starter output shaft 8. In other words, the internal gear 6 is formed in the ring-shaped part 10 on the inner side out of double ring-shaped parts 10, 11 which are extended in the axial direction on the outer circumference of the flange 9, and the ringshaped part 11 on the outside is constituted as a cushioning part, and an elastic member 13 such as rubber is interposed between both ring-shaped parts 10 and 11.

摘要： PURPOSE:To reduce high-frequency sound easily and surely by providing a cushioning member on a pinion gear to reduce high-frequency sound generated by contacting of an end surface of the pinion gear with another metallic plane when the pinion gear returns to a rest position. CONSTITUTION:When a magnetic switch is turned on, a shift lever 8 is brought into contact with the rear end 1c of a pinion gear 1 to cause it shifting to an end surface 2a of a ring gear 2 in an engine. Simultaneously, electric current flows through a motor to rotate it, and the pinion gear 1 engages with the ring gear 2 to start the engine. When the magnetic switch is turned off after the engine is started, the pinion gear 1 is returned by a return spring 9 and the like to a rest position before it is operated. At this time, an end surface 3c of a spline tube 3 is brought into contact with an end surface 12b of a retaining ring 12, and a cushioning member 11 reduces a generated impact force. Therefore, it is possible to reduce high-frequency sound generated at the time of contact.
