ABSTRACT:
A power transmission mechanism between an engine starter and an engine capable of securely engaging the ratchet wheel of a rotatingly driven part with the lever-like engagement/disengagement member of a centrifugal clutch mechanism when the engine is started. The side face of the lever-like engagement/disengagement member facing the ratchet teeth of a second ratchet part is formed in such a shape that is recessed in a direction apart from the peripheral surface of the second ratchet part in an area starting at its pivoting part toward an engagement/disengagement claw part. The engagement/disengagement claw part formed at the tip of the lever-like engagement/disengagement member is engaged with the ratchet teeth of the second ratchet part by surface contact, and the ratchet teeth of a first ratchet part and the ratchet teeth of the second ratchet part are disposed at a prescribed phase difference.
