ABSTRACT:
In this driving force transmission apparatus, with a simple constitution employing a one-way clutch20instead of an electromagnetic clutch, the driving force derived from the motor33can be transmitted to the rotating shaft1during engine stops, and the driving force of the engine can be transmitted to the rotating shaft1during engine operations. Also, the pulley3is held against the connecting portion11and the fixed-side member26by means of first and second two ball bearings21, 30disposed axially adjacent to first and second inner cylinder portions6, 7, respectively, between which the opening portion5of the pulley2is interposed. This simple driving force transmission apparatus can switch between transmission and non-transmission of driving force from pulley to rotating shaft, and transmits the driving force of a motor directly to the rotating shaft in the non-transmission state.
