Claims (1)

[Scope of Claim for Utility Model Registration] (1) The tip of the output shaft extends beyond the part facing the ring gear and is rotatably supported on the housing, and the pinion gear is movable in the axial direction on this output shaft. In the starter motor device, a cylindrical portion is provided as an extension at the end edge of the pinion shaft on the ring gear side, and a proximal end side of a pinion gear stopper provided integrally with the output shaft is supported by the cylindrical portion. 1. A starter motor device, characterized in that the starter motor device is fitted internally so as to overlap with the portion of the starter motor. (2) The starter motor device according to claim 1, wherein a stepped portion is formed on the outer circumferential surface of the cylindrical portion and the outer circumferential surface of the gear stopper. (3) A starter motor device in which the tip of the output shaft extends beyond the portion facing the ring gear and is rotatably supported on the housing, and the pinion gear is supported on the output shaft so as to be movable in the axial direction. In this, the support mechanism for the output shaft of the pinion shaft supports a sleeve movably in the axial direction by spline fitting on the outer periphery of the output shaft, and the outer periphery of the sleeve is fixed to the inner periphery of the pinion gear via a bearing. The pinion gear is configured such that it is rotatably supported around the shaft, and a sleeve stopper is provided at the tip end of the pinion gear to block the sliding end surface to restrict movement of the sleeve and the bearing in the axial direction. A starter motor device characterized by: (4) A starter motor in which the tip of the output shaft extends beyond the portion facing the ring gear and is rotatably supported on the housing, and the pinion gear is supported on the output shaft so as to be movable in the axial direction. In the device, the support mechanism for the output shaft of the pinion shaft is such that the output shaft is rotatably supported on the outer periphery of the output shaft via a bearing fixed to the inner periphery of the sleeve, and the outer periphery of the sleeve is supported through a spline fitting. The pinion gear stopper is supported on the inner circumference of the pinion gear so as to be movable in the axial direction, and is integrally provided with the output shaft.The base end of the pinion gear stopper is formed into a cylinder, and the tip of the sleeve is fitted into the pinion gear so as to overlap it. A starter motor device characterized by:
