Construction of a continuously variable transmission device for a vehicle is achieved that, when a shift lever is shifted to a selection position for a direction opposite the traveling direction at that time, it is capable of preventing the vehicle from continuing to travel at high speed in a direction opposite the direction intended by the operator. When the shift lever is shifted to a selection position of a direction opposite the traveling direction at that time, and the vehicle speed is faster than a specified speed (V1), the connection of a clutch device that transmits power between a continuously variable transmission mechanism and a differential gear mechanism is disconnected, and the drive force from the drive source is prevented from being further transmitted to the wheels. As a result, it is possible to cause the vehicle to decelerate without accelerating even when the operator tries to move faster in the opposite direction, or when the operator steps on the accelerator pedal with the intention of accelerating in the opposite direction, and thus it is possible to prevent the vehicle from continuing to travel at high speed in the direction opposite the intended direction of the operator.
