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.

Abstract: 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.

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 recoil starter is provided which prevents malfunction, such as disengagement of a claw, after the engine is started repeatedly even if the starter is not made of a material of high intensity. A spring can be wound substantially precisely circularly. It is quite easy to mount a friction plate to the starter. Furthermore, this subassembly does not loosen after long-term usage. A rope guide can be easily mounted to the starter case, thus reducing the fabrication cost. The recoil starter can be placed and locked in position relative to a fan cover with high accuracy. When the ratchet is in its protruded position, the pivotal point of the ratchet is located radially inside a pulley around the position where the pulley engages the ratchet. A ratchet support portion is formed radially outside the pulley on the reel. The ratchet forms a beam supported at its both ends. The beam acts against a force exerted by the pulley due to a resistance produced when the engine is started. A cover is mounted at the top end of the support portion to prevent the ratchet from moving toward the top end of the ratchet. A cylindrical engaging portion is formed on the outer surface of the stem of the starter case. One end of the spring engages this engaging portion. A rope takeout port is formed in the outer surface of the case such that the rope is payed out while tilted upwardly from a horizontal plane. The rope guide made of a hard material and acting to guide the rope is fitted over the case between the rope takeout port and the reel.
