Abstract
In an engine starting apparatus, together with a one-way clutch, a pinion is pushed toward a ring gear of an engine mounted in a vehicle. The one-way clutch has an idling torque smaller than a torque of the ring gear that tries to turn the pinion when the pinion is pushed to the ring gear. By a control device, a pinion pushing device is enabled to operate when i) the revolution speed of the ring gear is larger than a revolution speed of the pinion and ii) a relative revolution speed between the revolution speed of the ring gear and the revolution speed of the pinion is a desired value.
