ABSTRACT:
A starter includes a motor, an output shaft, a first spline connection member disposed between the motor and the output shaft, a pinion to be engaged with a ring gear of an engine, a second spline connection member disposed between the output shaft and the pinion, a pinion spring to apply its spring force to the pinion toward the ring gear, a lever, an electromagnetic switch to drive the output shaft toward the ring gear when the electromagnetic switch is excited and to operate the motor when the lever moves to a prescribed position, a drive spring to apply its spring force to the pinion when the electromagnetic switch drives the output shaft toward the ring gear. The first and second spline connection members rotate the pinion relative to the output shaft an angle more than a half of a pitch of the pinion when the helical connection member is driven by the electromagnetic switch toward the ring gear.
