Abstract:
In this toroidal continuously variable transmission unit, a carrier 100 and a disc 2 is brought into direct friction contact with each other, and power transmission between the carrier 100 and the disc 2 is implemented by friction force. Because of this, the necessity of machining a gear or claw on the disc or carrier, which has conventionally be done, is obviated, whereby a manufacturing process can be shortened and manufacturing costs can largely be reduced.
