Abstract:
1. A recoil starter comprising: a case that is disposed on an engine and that includes a reel support shaft formed thereon; a rope reel rotatably disposed on the reel support shaft; a recoil rope wound on an outer peripheral portion of the rope reel to rotate the rope reel in an engine start direction; a recoil spring that rotationally energizes the rope reel in an opposite direction of the engine start direction to rewind the recoil rope; a cam engaged with a drive pulley connected to an engine through a clutch mechanism to transmit a rotation power of the rope reel to the drive pulley; a power storing spring interposed between the rope reel and the cam; and a ratchet mechanism interposed between the rope reel and the cam; wherein the ratchet mechanism separates the rope reel and the cam from each other when the rope reel is rotated in the engine start direction; wherein the ratchet mechanism connects together the rope reel and the cam when the rope reel is rotated in the opposite direction to the engine start direction; wherein the ratchet mechanism includes: wherein when the ratchet member disengages from the cam, when the rope reel rotates in the engine start direction, the ratchet member is pulled away from the cam, and wherein when the ratchet member engages with the cam, when the rope reel rotates in the opposite direction to the engine start direction, the ratchet member is pulled away from the inner peripheral surface of the case.
