PROBLEM TO BE SOLVED: To efficiently perform engagement and disengagement of a clutch by preventing hydraulic pressure loss of a slave cylinder during operating the clutch, to prevent the working fluid and lubricant of the clutch from being mixed with each other, and to downsize the slave cylinder and a transmission case. SOLUTION: The slave cylinder 1 is airtightly fitted on one side wall 2a of the transmission case 2. Two lines of sealing grooves 5a, 5b are recessed on the outer periphery of a piston 5 inserted into a cylinder hole 4 in the slave cylinder 1. O-rings 6, 7 for sealing the cylinder hole 4 are fitted into the sealing grooves 5a, 5b. |
