Abstract
A recoil starter wherein unidirectional rotating means is enabled to sustain a larger magnitude of torque, obviating the employment of parts which are high in mechanical strength, in rigidity and in working precision, thus making it possible to reduce the weight and the manufacturing cost thereof. The recoil starter includes a driving member, a driven member, and buffering/power-accumulating means interposed between the driving member and the driven member. The buffering/power-accumulating means is enabled, during the driving process, to accumulate the power supplied through the driving process while alleviating impact to the driven member. The accumulated power is subsequently employed to drive the driven member. The recoil starter includes a spiral spring mechanism having a housing adjacent to the driving member, an actuating pulley adjacent to the driven member, a buffering/power-accumulating member interposed between the housing and the actuating pulley, and unidirectional rotating means for permitting rotation of the housing unidirectionally in a driving direction, where the unidirectional rotating means is disposed on the outer peripheral side of the spring housing.
