ABSTRACT:
A clutch mechanism disposed between an engine (2) and a transmission (3) includes an input part (10) supplied with torque from the engine (2), an output shaft (11) of the transmission (3), a planetary gear train (12) and a clutch device having clutches (13) and (14). The planetary gear train (12) has a sun gear (31), planetary gears (32) meshing with the sun gear (31), a carrier (34) carrying the planetary gears (32), and an ring gear (33) meshing with the planetary gears (32). The clutch device is operable to selectively engage and disengage portions of the planetary gear train (12) such that one of two differing power transmission paths may be used to transmit torque. One power transmission path transmits torque at a lower speed than the other transmission path.
