ABSTRACT:
A recoil starter having improved durability by inhibiting excessive deformation of a damper spring, and capable of receiving a damper spring with high shock-absorbing and force-storing capabilities. The recoil starter includes a rope reel and a cam which are rotated by pulling a recoil rope, so that a rotation of the cam is transmitted to an engine via a ratchet mechanism to start the engine. A damper spring which couples the rope reel and the cam to each other has, at opposite ends thereof, engaging portions radially movably supported by holding portions of the rope reel and the cam, respectively, so that substantially the overall length of the damper spring winds and tightens uniformly around outer peripheral surfaces of both bosses of the rope reel and the cam due to a startup resistance of the engine.
