Abstract
A recoil starter includes: a rope reel on which a recoil rope, one end of which is held on an outside of a starter case, is wound and which is fitted turnably on a reel pivot formed on an inside of the starter case; a recoil spring that turns and energizes the rope reel in a direction along which the recoil rope is rewound; a cam member one end of which is fitted turnably onto the reel pivot to oppose to the rope reel and which transfers a turning to an engine side via a ratchet mechanism; and a coil spring-like damper spring both ends of which are engaged with the rope reel and the cam member respectively; a bearing portion that supports turnably the cam member; and a dust cover provided integrally with the starter case.
Claims4
A recoil starter comprising:
- a rope reel on which a recoil rope, one end of which is held on an outside of a starter case, is wound and which is fitted turnably on a reel pivot formed on an inside of the starter case;
- a recoil spring that turns and energizes the rope reel in a direction along which the recoil rope is rewound;
- a cam member one end of which is fitted turnably onto the reel pivot to oppose to the rope reel and which transfers a turning moment to an engine side via a ratchet mechanism;
- a damper spring having two ends engaged with the rope reel and the cam member respectively, whereby an engine is started by transferring a turning force of the rope reel to the cam member via an elasticity of the damper spring;
- a bearing portion that turnably supports the cam member;
- and
- a dust cover provided integrally with the starter case to define a sealed space in which the rope reel, a recoil spring, at least a portion of the cam member and the damper spring are housed.
