Abstract: The invention relates to a power transmission mechanism between an engine starting device and an engine. A side surface shape of a lever-shaped engaging and disengaging member (107) in a side facing to a ratchet wheel (120) of a rotation driven portion is formed in a concave shape concaved in a direction away from the wheel (120). The lever-shaped engaging and disengaging member (107) is engaged with and disengaged from a centrifugal clutch mechanism of the engine engaging with and disengaging from the ratchet wheel (120). A first engaging and disengaging lever (141) is engaged with the ratchet wheel (120), a sufficient force to start the engine is accumulated in a force accumulating power spring (131), thereafter the engagement of the first engaging and disengaging member (141) is disconnected by a manual operation, and the ratchet wheel (120) is rapidly rotated by releasing the accumulated force in the force accumulating power spring (131). When the ratchet wheel (120) starts rotating at this time, a stop position of the lever-shaped engaging and disengaging member (107) is not determined, and it is often the case that the lever-shaped engaging and disengaging member (107) and the rapidly rotating ratchet wheel (120) are not originally in the engaged state. As a result, leading ends of the engagement surfaces come into collision with each other so as to be broken, and it is hard to start the engine. However, the lever-shaped engaging and disengaging member (107) is not broken on the basis of the shape and the structure peculiar to the invention, and it is possible to securely start the engine regardless of the stop position thereof and an abrasion of the first engaging and disengaging lever (141).

Abstract: A recoil starter capable of preventing vibration of a damper spring due to vibrations of an engine caused during running of the engine, to thereby restrain abrasion of a rope reel, a cam and the like which are made of a plastic material, resulting in the durability of the recoil starter being enhanced. The recoil starter includes a drive section comprised of a rope reel which is rotated by pulling a recoil rope and a cam for transmitting the rotational force of the reel to a crankshaft of the engine through a one-way rotative transmission mechanism. A damper spring in the shape of a torsion coil spring is held in annular recesses formed in joint surfaces of the rope reel and cam to face each other while the damper spring is resiliently distorted, so that the rope reel and the cam are rotatingly coupled with each other through the damper spring.

Abstract: A recoil starter is disclosed which enables a ratchet member to be manufactured at a reduced cost and which is capable of obtaining a sufficient strength and reducing a size and weight thereof without increasing a thickness of a rope reel and the like. The ratchet members are mounted on the rope reel so as to engage with a control member that is rotatably attached to a reel shaft with a rotational resistance imparted thereto, so that the ratchet members are turned radially outwardly to engage with a drive pulley, to thereby allow the drive pulley to rotate integrally with the rope reel. The ratchet members are each formed of a rod material having a circular section by bending the material and are each pivotally supported on a side surface of the rope reel.
