ABSTRACT:
In an overhung type starting electric motor, a pinion part of a movable pinion cylinder is made smaller in inside diameter than a clutch inner part and a cylindrical part thereof, and a stepped part is provided between a helical spline part and the small diameter part of a rotary shaft in such a manner that a very small gap is formed between the stepped part and the inner cylindrical wall of the clutch inner part of the movable pinion cylinder, and a very small gap is formed also between the small diameter part of the rotary shaft and the inner cylindrical wall of the pinion part of the movable piston cylinder. A misalignment preventing ring is fitted in the clutch outer of an overrunning clutch to be slidable on the stepped part.
