Problems solved by technology

[0020] However, since the mass of the pinion moving body in the pinion tube conversion structure is large in the first position, the electromagnetic switch needs to be enlarged
[0021] In addition, the inner circumference of the washer contacts the circumference of the pinion tub

Embodiment Construction

[0062] Aspects of the present invention will be described below with reference to the accompanying drawings.

[0063] 【aspect】

[0064] 【Composition of the first aspect】

[0065] use figure 1 The composition of the starter 1 of the first aspect will be described.

[0066] The starter 1 is installed in an engine compartment (not shown) of a vehicle, and starts an internal combustion engine (not shown).

[0067] The starter 1 has an electric motor 2, an electromagnetic switch 3, a pinion 4, a switching lever 5, a transmission shaft 6, a housing 7, a one-way clutch (not shown) and the like.

[0068] Hereinafter, the side provided with the pinion 4 is defined as a first end side in the axial direction, and the side provided with the electric motor 2 is defined as a second end side in the axial direction, as shown in the drawings shown.

[0069] In starter 1, shift lever 5 is shifted by electromagnetic switch 3 to engage pinion 4 to ring gear 8 of the engine, and torque of electr

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.
