PROBLEM TO BE SOLVED: To provide a driving device for a vehicle which resists a centrifugal force and allows an engagement/disengagement operation of a clutch in a short time with a simple constitution. SOLUTION: A clutch mechanism 40 consists of an input member 25, an output member 26, a cylinder 27, a piston member 46 which is advanced by a liquid pressure of a liquid pressure chamber 49 formed between a piston part 46a and a bottom of a cylinder 27 to press a friction plate and a separate plate to be engaged with each other in a pressing part 55, a cancel chamber 54 surrounded by an inner peripheral hole 55a of the pressing part 55, the back of the piston part 46a, and a wall member 56 fitted into the inner peripheral hole, a bias member 58 for biasing the piston member 46 in a direction of disengaging the clutch, an orifice 57 formed in the piston part 46a for communicating between the liquid pressure chamber 49 and cancel chamber 54, an inflow port 61 communicated with a liquid pressure source or reservoir 72 to open a liquid pressure chamber 49, and an outflow port 62 opened to the cancel chamber 54 for communication with the reservoir.
