PROBLEM TO BE SOLVED: To resolve the difference in the connection performance of a clutch to swap the clutch when the outputs of a crankshaft are different.SOLUTION: A twin clutch device includes first and second clutches which are coaxially disposed on the main shaft of a transmission body to connect/disconnect the input of a driving force to the main shaft, a cam shaft 65 rotatably supported in an engine case, first and second cams 66 and 67 which are mounted on the cam shaft 65 and have difference in phase from each other, and pistons 63 and 64 abutting the first and second cam 66 and 67 to operate the first clutch, wherein the cam crest 73 of the first cam 66 and the cam crest 75 of the second cam 67 are configured so that a displacement of the pistons 63 and 64 abutting the first cam 66 and the second cam 67 occurs multiple times per rotation relative to the rotation angle of the first cam 66 and the second cam 67 and an overlap in different amount of displacement occurs. |
