RECOIL STARTER HAVING SIZE AND WEIGHT REDUCED RECOIL STARTER HAVING SIZE AND WEIGHT REDUCED, FACILITATING STARTING OF AN ENGINE AND REDUCING THE NUMBER OF PARTS AND THE MANUFACTURING COST

摘要

PURPOSE: A recoil starter is provided to facilitate starting of an engine, to reduce the number of parts and the manufacturing cost, and to achieve miniaturization. CONSTITUTION: A recoil starter comprises a casing(1) having a reel shaft(2); a rope reel(4) rotatably supported to the reel shaft; a recoil spring(5) rotatably pressing the rope reel in the re-winding direction of a recoil rope(3); a cam(9) engaging with a driving pulley(6) connected with an engine through a clutch mechanism(7) to transmit rotation to the driving pulley; and a buffering accumulative force unit(12) arranged between the rope reel and the cam. A drum part(4a) on which the recoil rope is wound is formed to the outer periphery of the rope reel. The rotational force of the rope reel accumulated to the buffering accumulative force unit is transmitted to the driving pulley through the cam and the engine is started. A ratchet mechanism(14) is arranged between the rope reel and the cam. When the rope is rotated in the starting direction of the engine, the ratchet mechanism separates the rope reel and the cam. When the rope reel is rotated in the opposite direction of the starting direction of the engine by the rotational force accumulated to the recoil spring, the ratchet mechanism interconnects the rope reel and the cam and the cam is rotated reversely together with the rope reel.
