PURPOSE:To prevent generation of damage at each part of rotational transmission even if a starting switch is turned on during the inertia rotation of an engine and a starter and a pinion is engaged with a ring gear again and the abnormal shock is applied. CONSTITUTION:An internal gear frame of an epicyclic gear reduction gear is formed freely to turn against a front bracket, and a front cylinder part of this internal gear frame works as a clutch inner, and a clutch outer is arranged through a roller, and this clutch outer is fixed to the front bracket to form a first over-running clutch for transmitting reduction of the rotation by the epicyclic gear reduction gear to an output shaft, and a second over-running clutch is installed to the output shaft to rotate a pinion, and the shock absorbing capacity is increased by two pairs of over-running clutches. |
