PROBLEM TO BE SOLVED: To prevent the durability of a clutch plate from degrading in the half-connection state of an advance clutch when idling an engine while stopping. SOLUTION: When a sun gear 17 and a carrier 21 are driven and connected by connecting an advance clutch 23, a rotation of an input shaft 13 and the sun gear 17 is transmitted to an input shaft 15 of a continuously variable transmission 14 as such. When a ring gear 18 is fixed by connecting a retreating brake 22, the rotation of the input shaft 13 and the sun gear 17 is reversed and transmitted to the input shaft 15 of the continuously variable transmission 14. Since a clutch drum 23 packaging an operation piston 23a of the clutch 23 is connected to the carrier 21, i.e., an output element, a revolution number of the clutch drum 23c is not increased even when an engine 10 is kept idling while stopping. Further, it can be avoided that a centrifugal pressure is generated in an operation fluid pressure chamber 23e separated by the clutch drum 23c and the operation piston 23 and it can be prevented that the operation piston 23a makes the clutch 23 to a half-connection state by the centrifugal pressure.
