PROBLEM TO BE SOLVED: To easily provide an oil passage without hindering durability in a forward movement and backward movement selector device for a vehicle using a single pinion type epicyclic gear device. SOLUTION: When traveling forward, a forward movement clutch 44 is engaged to directly transmit the power from a turbine shaft 26 to an input shaft 48, and a hindrance of durability due to a large load to be locally applied to a tooth surface of each gear of the epicyclic gear device 42 can be prevented. The forward movement clutch 44 is arranged in a turbine 26 side, and connected to the input shaft 48 through an inserting member 54, and a hydraulic cylinder 52 is supported by a support part 34s of a first partition plate 34, and an oil passage for supplying the hydraulic fluid is provided in the first partition plate 34. A hydraulic cylinder 60 of a backward movement brake 46 is provided in a second partition plate 38, and an oil passage for supplying the hydraulic fluid is provided in the second partition plate 38. With this structure, a structure for providing each oil passage is simplified.
