Patent ID: 8801556

Claim:
A power transmitting device, comprising: an input shaft transmitting power from an engine to a change gear; a transmission shaft transmitting power transmitted from the input shaft to a rotor of a generator motor; and a switching device disposed on a power transmission route from the input shaft to the transmission shaft and switching transmitting direction of power between the input shaft and the transmission shaft, wherein the switching device includes: a first clutch blocking transmission of power from the transmission shaft to the input shaft while transmitting power inputted from the input shaft to the transmission shaft, where the power transmission from the input shaft to the transmission shaft can be blocked; and a second clutch transmitting power inputted from the transmission shaft to the input shaft while blocking transmission of power from the input shaft to the transmission shaft; wherein the first clutch transmits power by means of sprag that is retained by a retainer; wherein a load application device is provided having a motor which operates to tilt the sprag of the first clutch toward a counter-self-lock direction; and wherein the retainer for the first clutch comprises a retaining part that retains the sprag, and a retainer load transmitting part that is installed to extend toward a direction crossing the axis from the retaining part where the retainer load transmitting part transmits a load from the load application device via a gear mechanism.
