Abstract
In this driving force transmission apparatus, with a simple constitution employing a one-way clutch 20 instead of an electromagnetic clutch, the driving force derived from the motor 33 can be transmitted to the rotating shaft 1 during engine stops, and the driving force of the engine can be transmitted to the rotating shaft 1 during engine operations. Also, the pulley 3 is held against the connecting portion 11 and the fixed-side member 26 by means of first and second two ball bearings 21, 30 disposed axially adjacent to first and second inner cylinder portions 6, 7, respectively, between which the opening portion 5 of the pulley 2 is 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.
