Claims

[Scope of utility model registration request]

The outer part of the overrunning clutch, which rotates together with the armature rotating shaft, and the inner part of the overrunning clutch, which is connected via a roller, are supported so as not to be able to move forward in a bearing installed in the front housing. A starter motor is provided with a helical spline around the periphery that engages with the pinion, and the helical spline applies rotational force from the inner to the pinion. A starter motor characterized in that the outer diameter of the collar is larger than the opening diameter of the front end of the front housing.
