ABSTRACT:
A coaxial type starter used to start an engine of a vehicle is disclosed. The starter comprises first and second bearings which are respectively disposed between the outer circumferential portion of a carrier of an epicyclic reduction gear which is formed integral with a clutch outer member of an overrunning clutch and a fixed portion of the starter and between the inner circumferential portion of the carrier and the outer circumferential portion of an armature rotary shaft of a d.c. motor. Accordingly, the carrier of the epicyclic reduction gear is prevented from becoming eccentric by the first bearing, and the armature rotary shaft of the d.c. motor which is supported by the carrier through the second bearing is also prevented from becoming eccentric. Thus, it is possible to eliminate any risk of the planet gears of the epicyclic reduction gear being damaged or generating noise.
