The engine starter includes: a starter motor; a pinion unit (30) for sliding in an axial direction on an output shaft of the starter motor; and a ring gear (100) which meshes with a pinion pushed out by a push-out mechanism (60) and receives a transmission of a rotational force of the starter motor to thereby start an engine, and the pinion portion (30) includes a pinion gear divided in the axial direction into two pinion gears which are a first pinion gear (35) having a protruded shape for synchronization, for first colliding with the ring gear upon start of meshing with the ring gear, and a second pinion gear (34) for serving to transmit the rotational force after the meshing. |
