内燃機関始動装置。[Claims for Utility Model Registration] It has a plurality of cam protrusions protruding from the outer peripheral surface, one side of each cam protrusion serves as a clutch pawl abutting part, and each clutch pawl abutting part faces forward in the direction of rotation. a clutch cam that is rotationally driven in a state in which the clutch cam is facing upward; a drive mechanism that rotationally drives the clutch cam using a starting electric motor as a drive source; a clutch pulley that has a peripheral wall surrounding the clutch cam and is coupled to an output shaft of an internal combustion engine; The clutch pulley is attached to the inner side of the peripheral wall of the clutch pulley in such a manner that it can rotate between a connecting position where it contacts the clutch pawl abutting portion and a disengaging position where it separates from the clutch pawl abutting portion, and is supported by a spring on the side of the connecting position. In the internal combustion engine starting device, the clutch pawl is biased and rotated toward the disengaging position by centrifugal force generated by rotation of the clutch pulley, wherein the clutch cam is formed in an annular shape, and the clutch pawl of each cam protrusion An inclined surface connected to the outer circumferential surface of the clutch cam is formed on a portion opposite to the abutting portion, a plurality of protrusions protruding radially inward are formed on the inner circumferential portion of the clutch cam, and A clutch cam driving member having a plurality of driving protrusions on an outer peripheral portion protruding from an inner peripheral surface of the clutch cam is rotatably arranged, the clutch cam driving member is coupled to an output portion of the drive mechanism, and the clutch cam is connected to an output portion of the driving mechanism. The drive member has a flange portion at an end located on the opposite side from the drive mechanism, the flange portion abuts against the end portion on the opposite side from the drive mechanism of the clutch cam, and the drive protrusion of the clutch cam drive member and An internal combustion engine starting device characterized in that a damper is disposed between the clutch cam and the protrusion, and the clutch cam driving member is coupled to the clutch cam via the damper.
