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. Before the impact acts on the pinion gear, the coil spring is subjected to a given initial load. When the impact acts on the pinion gear, the coil spring absorbs it transmitted through the buffer rubber. The cover in which the coil spring is stored has a flange which is held from moving to the pinion gear in response to expansion of the coil spring, while it is permitted to move to the motor in response to contraction of the coil spring. This eliminates a risk that mechanical noise occurs when the pinion gear is advanced and then brought into mesh with the engine.
