Abstract: A starter includes a coil spring disposed between a pinion gear and a motor and a buffer rubber disposed between the pinion gear and the coil spring. When the pinion gear is subjected to a reactive force from an engine, the buffer rubber absorbs the impact.

This eliminates a risk that mechanical noise occurs when the pinion gear is advanced and then brought into mesh with the engine.
