Abstract: A starter for an internal combustion engine includes a rotating shaft formed with a helical spline on an outer periphery thereof and which rotates by a rotation of a motor, a pinion gear helically splined to the rotating shaft and movable in an axial direction of the rotating shaft along a tooth surface of the helical spline, a lever receiving member disposed opposing an end surface in an axial direction of the pinion gear, moved by receiving an axial pushing force by a pushing member, and causing the pinion gear to engage with a ring gear of the internal combustion engine by a movement thereof, and a buffer member for restricting a movement of the pinion gear in a rotational direction when the pinion gear moves along the teeth surface of the helical spline.

Abstract: A washer is held by being sandwiched in an axial direction by a pinion and a holder. Here, although the washer is inexpensive, it has high planar accuracy. Then, by sandwiching the washer in the axial direction between the pinion and the holder, a metal surface of the inexpensive washer with high planar accuracy can be used as a contacting surface that contacts a holder side slide-contacting surface directly. Furthermore, another metal surface of the washer can also be directly contacted to a pinion side slide-contacting surface. Thereby, wear caused by a slide-contacting rotation of the holder can be reduced without raising costs of parts and processing in the starter that adopts a pinion shift structure.
Abstract translation: 通过小齿轮和保持器沿轴向夹持垫圈。 这里，虽然垫圈价格便宜，但平面精度高。 然后，通过将垫圈沿轴向夹在小齿轮和保持器之间，可以使用具有高平面精度的便宜的垫圈的金属表面作为直接接触保持器侧滑动接触表面的接触表面。 此外，垫圈的另一金属表面也可以直接接触小齿轮侧滑动接触表面。 由此，可以降低由保持器的滑动接触旋转引起的磨损，而不会增加采用小齿轮变速结构的起动器中零件的成本和加工。

Abstract: A starter includes a coil spring disposed between a pinion gear and a motor and a buffer rubber disposed between the pinion gear and the coil spring. When the pinion gear is subjected to a reactive force from an engine, the buffer rubber absorbs the impact. Before the impact acts on the pinion gear, the coil spring is subjected to a given initial load. When the impact acts on the pinion gear, the coil spring absorbs it transmitted through the buffer rubber. The cover in which the coil spring is stored has a flange which is held from moving to the pinion gear in response to expansion of the coil spring, while it is permitted to move to the motor in response to contraction of the coil spring. This eliminates a risk that mechanical noise occurs when the pinion gear is advanced and then brought into mesh with the engine.

Abstract: A first distance between a position where a point-of-action end abuts at a rear end surface of a push-side abutting portion (flat washer) forming a part of holder and a rotational axis of a pinion, and a second distance between a position where the pinion abuts at a front end surface and the rotational axis of the pinion have the relation of first distance>second distance. Thereby, after starting an engine, even when the pinion is rotated at high speed, the push-side abutting portion is less likely to rotate and remains stationary relative to the lever, and even though the push-side abutting portion begins to rotate, it is rotated at a lower speed than the pinion.
