Claims

[Claims for Utility Model Registration] (1) A driven clutch member arranged concentrically with and fixed to the rotating shaft of an internal combustion engine, a starting electric motor, and a driven clutch member that is rotationally driven by the starting electric motor. and a starter drive unit formed by unitizing a drive side clutch member which is connected from the inside to the driven side clutch member when the starter drive unit is rotationally driven. In an internal combustion engine starting device that is attached to an internal combustion engine in a state where the driven clutch member is positioned concentrically with the driven clutch member, the driven clutch member has a cylindrical outer circumferential surface extending concentrically with the central axis thereof, and The starter drive unit has a dustproof peripheral wall concentrically surrounding the outer periphery of the driven clutch member, and a cushion member that contacts the outer peripheral surface of the driven clutch member is attached to the inner periphery of the dustproof peripheral wall. An internal combustion engine starting device characterized by: (2) a driven clutch member disposed concentrically with and fixed to the rotating shaft of the internal combustion engine, a starting electric motor, and a rotationally driven clutch member provided to be rotationally driven by the starting electric motor; a starter drive unit formed by unitizing a drive side clutch member which is coupled from the inside to the driven side clutch member when the starter drive unit is in a state where the drive side clutch member is concentric with the driven side clutch member. In an internal combustion engine starting device that is attached to an internal combustion engine in a state where the starter drive unit is positioned at a position further outside the outer periphery of the drive side clutch member, the starter drive unit has an outer periphery extending concentrically with the central axis of the drive side clutch member. an annular member having a surface on the internal combustion engine side, the driven side clutch member having a dust-proof peripheral wall concentrically surrounding the outer peripheral surface of the annular member, and an inner periphery of the dust-proof peripheral wall. An internal combustion engine starting device characterized in that a cushion member is attached to the outer circumferential surface of the annular member.
