Abstract

While engaging mechanically with one of the two internal gears (25) and (29) used for two gear reduction systems and suppressing rotation of the internal gear of one of these, there is provided a gear-switching member (34) that permits rotation of the other internal gear, the gear-switching member (34) is connected with a rotating friction plate (39) of an impact-absorbing mechanism 8 via a yoke (36). Thereby, if excessive shock is transmitted to an output shaft (3) of the starter from an engine side, rotation load will be transmitted to the rotating friction plate (39) via the yoke (36) from the gear-switching member (34) that engages with the internal gear (25) or the internal gear (29). Consequently, when the rotating friction plate (39) rotates resisting frictional force, the excessive shock can be eased and a power transfer system of the starter can be protected from excessive shock.
