Abstract:
1. A starting device of an engine, comprising: a starter gear driven by a starter motor; a starter member connected to an engine starting shaft, the engine starting shaft defining an axial direction of the starting device; and a starter clutch located between the starter member and the starter gear to transmit rotary motion from the starter gear only to a side of the starter member; wherein the starter clutch is provided with an outer race that rotates with the starter member, and a clutch member interposed between the outer race and the starter gear; the starter member has a through hole formed therein so as to oppose the outer race in the axial direction; a stepped section is defined between a radially outer portion of the outer race which faces a radially outer edge of a periphery of the through hole and a radially inner portion of the outer race which is in contact with the clutch member; and the stepped section defines a contour of the outer race such that the radially outer portion of the outer race is thinner in the axial direction than the radially inner portion of the outer race.
