Abstract
A pullback starter comprises a rope pulley rotatably mounted on an axle and on which a driving coupling element is mounted for pivotal movements to constitute an engageable and disengageable coupling of a clutch for the drive shaft of an internal combustion engine. A coil spring surrounds the axle and is braked against rotation thereon by friction. The spring has first and second legs protruding from the axle at opposite ends of the spring. A locking member engaged by the first leg is rotatably mounted in the coupling element for rotation relative thereto between locking and unlocking positions. A first stop is carried by the coupling element, second and third stops are carried by the locking member, the second stop being arranged so that, when the locking member is in its unlocking position, the second stop engages the first stop, and the third stop being arranged so that, when the locking member is in its locking position, it prevents pivotal movement of the coupling element, a further stop is carried by the coupling element and is adapted to engage the second leg so as to define the locking position, and a safety stop is carried by the first leg and engages the second leg to act on the latter in a sense tending to untwist the spring.
