ABSTRACT:
In a starter unit, the internal gear frame of an epicycle reduction gear is set rotatable with respect to the front bracket, and a first over-running clutch is made up of a clutch outer fixed to the front bracket, and a clutch inner which is the front end portion of the internal gear frame, and a second over-running clutch which is a conventional over-running clutch is mounted on the output shaft. The provision of the two over-running clutches eliminates the difficulty that, when the start switch is turned on during the inertial rotation of the engine or starter unit, the pinion is reengaged with the ring gear, so that abnormal shock is applied to the side of the starter unit to damage the rotation transmitting members.
