Abstract: 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.

Abstract: The present invention achieves construction of a toroidal continuously variable transmission of which manufacture, management and assembly of parts can be performed easily, reduction of cost is easy and speed change operation is stabilized. This construction comprises support holes 28 having a circular cross section that are formed in part of the outer rings 16f, column shaped anchor pins 26 that, when fitted and fastened inside the support holes 28 with an interference fit, part of the anchor pin 26 protrudes from the inside surface of a concave section 23e of the outer ring 16f, and anchor grooves 27 that are formed in cylindrical convex surfaces 22e of support beam sections 9f of the trunnions 7f in the circumferential direction of the cylindrical convex surfaces 22e; wherein, the engagement sections where the parts of the anchor pins 26 engage with the anchor grooves 27 can support torque that is applied to the power rollers 6a as the input and output disks 2, 5 rotate.
