A starter is provided, which includes an intermediate gear connected to an intermediate shaft, and engaging with and driven by a pinion gear which is connected to an output shaft of a motor. The intermediate gear engages with a ring gear of an engine to crank up the engine when shifted together with the pinion gear in axial directions of these shafts via a retainer which is slidably supported by both of these shafts. A clutch supported by the shaft of the motor causes this shift by pushing the retainer in its axial direction. The clutch and the intermediate gear, each being defined by its outermost diameter, overlap with each other in the radial direction between these shafts. This overlap reduces stress acting on the retainer when the intermediate gear engages with the ring gear, thus reducing thickness of the retainer and the axial length of the starter.
