Claims

[Claims for Utility Model Registration] (1) A rotating shaft, a pinion member disposed on the rotating shaft so as to be movable in the axial direction, and a pinion member disposed on the inner peripheral side of the pinion member so as to stop the pinion member from moving in the axial direction. A stopper ring fixed to the rotating shaft, and a bracket having a bearing portion for supporting the end portion of the rotating shaft, wherein the bearing portion of the bracket is provided to protrude to the inner circumferential end of the pinion member, and the pinion member An engine starting device characterized in that the shaft is moved in the axial direction on the outer periphery of the shaft bearing portion so as to mesh with a ring gear of the engine. (2) The shaft bearing part supports the rotating shaft via a sleeve bearing, and a dustproof member having a T-shaped cross section is interposed between the stopper ring and the sleeve bearing. Engine starting device as described in section.
