Abstract: A recoil starter capable of readily staring an engine and reducing the number of components and manufacturing costs thereof and reducing a size and weight thereof. The recoil starter is so constructed that a rotational force accumulated in a cushioning and force accumulating means interposed between a rope reel and a cam is transmitted via the cam to a drive pulley, to thereby start the engine. A ratchet mechanism is provided between the rope reel and the cam so as to uncouple the cam from the rope reel when the rope reel is rotated in an engine starting direction and so as to couple the cam to the rope reel when the rope reel is rotated in a direction opposite to the engine starting direction, thus rotating the cam and the rope reel together in said opposite direction.

Abstract: A recoil starter has a starter case provided around a starter shaft. A one-way clutch mechanism is formed between one end of the starter shaft and an engine. A reel is mounted rotatably on the starter shaft and a rope is wound in a groove of the reel. A first spiral spring has its ends fixed respectively to the starter case and reel and urges the reel in the direction in which the rope is taken up. A second spiral spring has its ends fixed respectively to the reel and transmits a rotational force of the reel to the starter shaft when the rope is drawn out. The peak load at the engine starting time is absorbed in the second spiral spring.

Abstract: A rotary cutter for a mower is provided wherein the cord delivering operation, which is necessary when the free end of the cord is worn, is carried out only when the rotary cutter is rotated at a low speed or is stopped. The rotary cutter includes a cord for cutting grass upon rotation thereof, a reel which holds the cord and allows delivering of the cord while the reel is intermittently rotated, a cover for a case which houses the reel, and a press body which protrudes downwardly from the case and is movable in an axial direction upon pressing so as to intermittently rotate the reel. A return spring for biasing the press body in a direction to protrude the press body from the case between the reel and the press body is also provided. The press body and the case engage each other such that the press body is slidable in an axial direction while preventing relative rotation with each other. By pressing the press body against the biasing return spring, a set of protrusions formed on the press body are detachably engaged with protrusions formed on the reel so as to intermittently rotate the reel.
