Starter for starting engine of vehicle, has roller comprising inner part whose outer periphery is formed in conical shape such that diameter decreases from side of pinion to opposite side of pinion in axial direction

摘要

The starter (1) has a roller (53) provided between an outer part (51) and an inner part (52) in a cam chamber. The outer part is formed in a conical shape such that an inner diameter of the outer part forming the cam chamber gradually increases from an opposite side of a pinion (6) to a side of the pinion in an axial direction. An outer periphery of the inner part is formed in a conical shape such that diameter decreases from the side of the pinion to the opposite side of the pinion in the axial direction.
