Claims

[Claims for Utility Model Registration] (1) An output rotating shaft that is driven in accordance with the rotation of an armature, and an overrunning clutch mechanism that is slidably fitted to the output rotating shaft, the output rotating shaft an overrunning clutch mechanism comprising a spline tube having spline teeth formed on its inner circumferential surface that mesh with a helical spline formed on the helical spline, and a pinion moving cylinder having a pinion for driving the engine;
a closing portion provided in at least a portion of the tooth groove of the helical spline formed on the output rotation shaft to restrict forward movement of the spline tube beyond a predetermined position; and a blocking portion provided at the front end of the pinion moving cylinder. A starter motor including a stopper device that protrudes into the interior thereof and comes into contact with an end face of the output rotating shaft when the pinion moving cylinder moves rearward to restrict rearward movement beyond a predetermined position. (2) The starter motor according to claim 1, wherein the stopper device comprises a stopper bolt screwed into a screw hole formed in the center of the front end of the pinion moving cylinder. (3) The utility model registration claim 1 is characterized in that the stopper device comprises a cotter pin that is inserted into a through hole formed in the center of the front end of the pinion moving cylinder and is engaged and held. Starter motor listed. (4) Utility model registration claim 2, characterized in that the stopper device further includes an adjustment washer that adjusts the amount of protrusion of the stopper bolt screwed into the screw hole within the pinion movement cylinder.
The starting motor described in section.
