った。However, with the above-mentioned conventional device, if the outer diameter of the pinion becomes larger than the inner diameter of the tail of the clutch cover, the clutch cover cannot be inserted from the pinion side, making it impossible to assemble the clutch cover. There was a problem in that it was inevitably restricted.

ことである。Therefore, the present invention provides: a pinion that meshes with a ring gear of an internal combustion engine; a spline tube that is helically spline-coupled to the shaft of a starter motor; a clutch outer that is connected to the spline tube and has a cam surface on its inner periphery; a clutch inner facing the cam surface of the clutch and forming a wedge-shaped space between the cam surface and having a step formed therein; and a clutch inner that is inserted into the wedge-shaped space;
a roller that transmits the rotation of the clutch outer to the clutch inch; a washer that is provided between the pinion side end surface of the clutch outer and the stepped portion and prevents the clutch inner from being removed; and a washer that prevents the clutch inner from being removed. The cylindrical portion has a cylindrical portion that covers an outer periphery, and a flange portion that is provided at one end of the cylindrical portion and engages with an end surface on the opposite side of the pinion of the clutch outer, and has an inner diameter smaller than an outer diameter of the pinion. The present invention provides an overrunning clutch for a starter, comprising: a clutch cover whose other end is squeezed into the washer portion;
