Abstract
In a starter, current is passed through a solenoid to use the generated electromagnetic force when pushing a pinion gear toward a ring gear, so that the ring gear is engaged with the pinion gear. For this purpose, the starter includes an electromagnetic solenoid, a spring for urging the pinion gear in a direction opposite to that of the electromagnetic solenoid, a connecting member connected to the pinion gear, a stopper for limiting movement of the connecting member to a predetermined position. Being urged by the spring, the pinion gear is disengaged from the ring gear, and the connecting member is retracted to a predetermined position. The starter includes a control circuit that implements control of passing a predetermined current through the solenoid after the disengagement but before retraction of the connecting member to the predetermined position.
