Abstract: A driving force transmission device for a hybrid vehicle is provided with a motor which drives a rotation shaft, and a connection/disconnection switching device which switches between connection and disconnection of driving force for driving wheels, the driving force being transmitted from an engine. The driving force transmission device is also provided with the auxiliary device driving mechanism, which includes one or more auxiliary device driving shafts for transmitting driving force to the in-vehicle accessory devices, one or more rotation transmission sections which transmit at least either engine's driving force or motor's driving force to one or more accessory device driving shafts via the rotation shaft, and a plurality of one-way clutches provided between the one or more rotation transmission sections and the one or more accessory device driving shafts.
