Starting motor with an intermediate gear

摘要

A starting motor with an intermediate gear wherein rotation of a rotating shaft of a DC motor is transmitted to a pinion in a one-way rotational direction by an overrunning clutch, and an intermediate gear supported rotatably and forward-and-backward slidably by an intermediate shaft retained by a front bracket through a bearing and in mesh with the pinion, meshes with a ring-gear of an internal combustion engine by a forward movement thereof thereby starting the internal combustion engine, characterized by that; a storage for a lubricant is provided at a middle portion of the intermediate gear in the axial direction, which is fixed to an inner diameter portion of the intermediate gear; and dust seals are provided in a bearing with metal back supported by the intermediate shaft and at both ends of the inner diameter portion of the intermediate gear.
