摘要： 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.

摘要： A recoil starter capable of starting an engine easily has a reduced number of components and a simple structure, and enables miniaturization and a cost reduction. A damper spring having one end thereof fixed to a reel and provided at the other end thereof with an operation section is arranged in such a manner that the operation section thereof is engageable with a centrifugal ratchet provided on a rotating member of the engine, so that a shock caused by the engine is absorbed by the damper spring and a rotating force from the reel is stored therein.

摘要： 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.

摘要： A damper spring having a torsion coil spring-like shape is placed on outer peripheries of bosses respectively formed on a rope reel and a cam. The ends of the damper spring are engaged with the rope reel and the cam, respectively, so that the rope reel and the cam are rotatingly coupled with each other. A wire member constituting the damper spring is formed so as to have a section shape in which at least one side is linearly formed, and the damper spring is formed by winding the wire member into a coil-like shape so that the linear portion of the wire member is placed on an inner peripheral side, thereby enabling the inner side face of the damper spring to be tightly wound in a wide area around outer peripheral faces of the bosses.
