<p>Provided is a clutch device capable of reducing energy loss caused by clutch-engaging pressure. The clutch device presses on a first friction plate (17) and a second friction plate (18) using an elastic member (20), by causing clutch-engaging pressure to act on a clutch piston (21) and moving the same in the clutch-engaging direction, then mechanically locking the position of the clutch piston (21) in this state by using a locking mechanism (32). The locking mechanism (32) is capable of varying the locking position thereof in the axial direction according to the maximum-elastic-displacement position of the elastic member (20). The clutch-engaging pressure is reduced according to the state of operation by a clutch-engaging-pressure reduction unit (42) when the locking mechanism (32) is locked.</p> |
