PROBLEM TO BE SOLVED: To properly hold clutch timing by securing and quickly discharging a centrifugal hydraulic pressure in a cancel oil chamber. SOLUTION: One clutch C3 is disposed on the outer diameter side of the other clutch C4 while being axially overlapped with each other. Hydraulic pressure is applied to a hydraulic servo 20 through an oil hole (b) of a clutch drum 22. The cancel oil chamber 28 formed in the rear of the hydraulic servo receives oil from the supply hole (a) of a boss part 22c through a gap A, and discharges it from the discharge hole (e) of the boss part 22c outward through the recessed groove (g) of a sleeve 81.
