    • 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.

    • In a starter, one end of a spring is connected with a pinion, whereas the other end of the spring is connected with an annular plate. A regulation claw of a regulation member for moving the pinion toward a ring gear is made separate from the spring which is flexed in the rotational direction of an output shaft so as to engage the pinion with the ring gear, when the pinion is brought into contact with the ring gear. Thus, appropriate setting of the specification of the regulation claw of the regulation member and that of the spring can be very easily accomplished. Further, because the specification of the spring can be independently appropriately set without difficulty, the spring is made more durable.
    • 在起动器中,弹簧的一端与小齿轮连接,而弹簧的另一端与环形板连接。 用于将小齿轮朝向齿圈移动的调节构件的调节爪与在输出轴的旋转方向上弯曲的弹簧分离,以便当小齿轮接触时将小齿轮与齿圈接合 与齿圈。 因此,可以非常容易地实现对调节构件的调节爪和弹簧的调节爪的规格的适当设定。 此外,由于弹簧的规格可以独立地适当地设定,所以弹簧更加耐用。

    • An electric rotating machine and manufacturing method of the same is provided that can securely press-fit magnetic poles against an inner circumference of a yoke with a cylindrical body. By directly contacting a first and second end portions of the cylindrical body and moving the same relatively, the diameter of the cylindrical body widens in the outer radial direction to press-fit the magnetic poles against the inner circumference of the yoke. Thus, the variation of the inner diameter of the magnetic poles that occurs due to the dimensional error in permanent magnet thickness and inner diameter of the yoke is absorbed by the relative movement of the first and second end portions. This stabilizes the fixing force of the magnet, and allows the magnet to be securely fixed to the yoke without excessive stress on the cylindrical body. Furthermore, the displacement of the magnetic poles can be restricted by bending axial ends of the cylindrical body radially outwardly.
    • 提供一种电动旋转机及其制造方法,其可以用圆柱体将磁极牢固地压配在轭的内圆周上。 通过直接接触圆柱体的第一和第二端部并使其相对移动,圆柱体的直径在外径向方向上变宽,以将磁极压配合到轭的内周。 因此,由于永磁体厚度的尺寸误差和轭的内径而产生的磁极的内径的变化被第一和第二端部的相对运动吸收。 这就稳定了磁铁的固定力,并且允许磁体牢固地固定在磁轭上,而不会对圆柱体产生过大的应力。 此外,可以通过径向向外弯曲圆柱体的轴向端部来限制磁极的位移。

    • An electric rotating machine which withstands mechanical and thermal loads applied thereto is provided. Coil arms and coil trunks are provided in roughly parallel orientation to the end faces of an armature core only through insulating rings and insulating spacers. Metal brush is disposed on coil arms constituting a commutator, whereby the overall length of the armature can be remarkably shortened. The coil arms are strongly pressed against and fixed to the side of armature core by a collar, so that the resistance to the centrifugal force can be remarkably improved. A cylindrical ring is circumferentially fitted on the upper coil trunks to prevent radially outward movement of the coil arms due to the centrifugal force. The coil arms disposed in a non-commutator side are made radially shorter than those disposed in the commutator side. Thus, electric resistance of an armature coil is reduced and radial movement caused by the centrifugal force is reduced.
    • 提供一种承受施加于其上的机械和热负荷的旋转电机。 线圈臂和线圈干线仅通过绝缘环和绝缘垫片以大致平行的方向设置在电枢铁芯的端面。 金属刷布置在构成换向器的线圈臂上,从而能够显着地缩短电枢的整体长度。 线圈臂通过轴环被强力地压靠在电枢铁芯的侧面上,从而能够显着提高对离心力的抵抗力。 圆柱形环周向地装配在上部线圈树干上,以防止由于离心力引起的线圈臂的径向向外移动。 设置在非整流子侧的线圈臂比放置在换向器侧的线圈臂的径向短。 因此,电枢线圈的电阻减小,由离心力引起的径向运动减小。

    • In a starter, to improve a heat dissipation performance, an axial length from the end of a starter housing fit into a clutch housing to a starter installation surface of the clutch housing is set to be longer than an axial length from the end of a starter motor not fit into the clutch housing to the starter installation surface. Alternatively, the exposed surface area of the starter housing fit into the clutch housing is set to be larger than the exposed surface area of the portion of the starter housing not fit into the clutch housing and the starter motor. With this configuration, the starter housing can be effectively cooled by whirling air flow in the clutch housing.

Concave portions extending from the outer circumference to the inner circumference are formed axially on the tubular portion. The center where the tightening force of the through bolts is applied is set between the hypothetical extension outer diameter and inner diameter of the tubular portion at the concave portion so that the tubular portion and the lid portions are tightened and fixed.
