Starter with improved one-way clutch structure

摘要

In a one way clutch of a starter having an outer member, inner member and rollers, a planet carrier is formed integrally with the outer member and through holes are formed avoiding cam chambers for rollers so as not to interfere with cam chambers formed in the inner circumferential surface of outer member. At one end portion of outer member, limiting portion for limiting the axial shifting of rollers is integrally formed, and at the other end surface, a limiting plate for limiting the axial shifting of rollers is provided and press-fitted into pins. The limiting portion may be replaced by another limiting plate. Through holes for the through holes are formed at locations where the outer member is radially thick, e.g., between circumferentially adjacent two of the cam chambers.
