ABSTRACT:
In a pinion shift device for a starter of the type employing a semicircular ring-shaped shift plate, the device is constructed such that the shift plate is easily assembled to a shift lever to be suitable for automatization, slide contact portions between the clutch body and the shift plate and/or between the shift flange and the shift plate are less subjected to overflow or exhaustion of grease and give rise to a smaller extent of wear, and thus service life of the device is prolonged. A semicircular ring-shaped portion of the shift plate is loosely fitted in an axial gap between a clutch body and a shift flange integral with a clutch sleeve. A recessed groove for storing grease therein is provided in at least one of paired opposite side faces between the semicircular ring-shaped portion of the shift plate and the clutch body as well as the shift flange. The shift lever and the shift plate are both molded using resin. Mutually fitting portions of the shift plate and the shift lever are constituted by projections and holes. Sloped surfaces serving as assembling guides are respectively formed in each end face of the projection and each side face around the hole.
