Patent ID: 8286604

Claim:
A starter for a small engine, comprising: a torque apply unit that applies a torque to a torque-accumulation spring arranged in a starter case; a rotating member provided in the starter case to transmit the torque accumulated in the torque-accumulation spring to a crankshaft of the engine; a driving pulley provided integrally with the crankshaft to be engaged with and disengaged from the rotating member; and a rotation regulation unit that restrains the torque accumulated in the torque-accumulation spring from being transmitted to the crankshaft, wherein the rotation regulation unit includes: a regulation ratchet provided on a rotating body at an eccentric position thereof, the rotating body being linked with the crank shaft to rotate therewith; and a pressing unit provided on an engine case to be engaged with the regulation ratchet and to regulate an operation of the regulation ratchet by a predetermined resilient force, and wherein the regulation ratchet is disengaged from the pressing unit by the torque accumulated in the torque-accumulation spring when the accumulated torque exceeds the resilient force, so that the rotating body and the crankshaft are rotated to thereby start the engine.
