    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.

    摘要翻译： 在旋转电机中，用于限制线圈端部的膨胀的轴环包括安装在电枢旋转轴上的凸台，从凸台径向延伸的凸缘和用于将线圈端朝向电枢铁心按压的按压部。 凸台的厚度大于凸缘的厚度，使得当线圈端部由于温度升高而膨胀时由法兰的偏转引起的力F1小于将凸起从该凸起移除所需的力F2 旋转轴。 力F1沿轴环与电枢铁芯分离的方向施加到凸台。 由于按压部分通过绝缘环将电枢铁芯的线圈端部压向电枢铁心，所以当电枢旋转时，线圈端部被离心力限制。

    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.
