<P>PROBLEM TO BE SOLVED: To provide a driving force transmission device of a hybrid vehicle that prevents a two-way clutch from being switched to an engagement state when traveling by the drive of an engine. <P>SOLUTION: Between an outer ring 22 and a holder 25 of the two-way clutch 19, a centering spring 50 is provided that is elastically deformed by the relative rotation of the outer ring 22 and the holder 25 and that returns and rotates the outer ring 22 to a neutral position where the engagement of a sprag 24 is released by the restoring elasticity to the facing surfaces of the outer ring 22 and an inner ring 23. The outer ring 22 of the two-way clutch 19 is made to rotate by vibration etc. when the vehicle travels by the drive of the engine to prevent the two-way clutch 19 from being engaged in the direction that impedes the rotation of rear wheels. <P>COPYRIGHT: (C)2009,JPO&INPIT |
