PURPOSE:To dispense with highly accurate control to smoothly change speed by interlocking a first clutch pressing member to connect and disconnect a first clutch mechanism with a second clutch pressing member to connect and disconnect a second clutch mechanism. CONSTITUTION:A drive plate 2 is fixed to a crank shaft 1, and a damper outer shell member 3 is fixed to the drive plate 2. The damper outer shell member 3 and a damper driven member 5 are elastically joined together by a spring 4, and a clutch outer shell member 6 is fixed to the damper driven member 5. A center plate 7 to engage with a connecting member 8 is fixed to the clutch outer shell member 6. First and second pressure plates 9a and 9b are respectively pressed by oil pressure supplied to first and second pistons 10a and 10b while receiving energizing force of a spring of the connecting member 8, and first and second clutch disks 11a and 12a are engaged with the center plate 7. Thereby, speed can be smoothly changed without shock without performing highly accurate control. |
