Claims

[Scope of utility model registration request]

The carrier includes a carrier formed by stacking endless hoops in multiple layers, a main body part and a carrier groove provided on the upper part of the main body part and having a hoop contact surface, and is continuously attached to the carrier via the carrier groove. A drive for a continuously variable transmission that consists of a large number of ■ blocks, is wound around the grooves of a pair of ■ type belt wheels, and is sent out from the input side ■ type belt wheel to rotate the output side ■ type belt wheel. The belt includes at least three end hoops arranged in series on the inner circumferential side of the innermost hoop of the carrier, and one end of each end hoop is connected to
A drive belt for a continuously variable transmission characterized by being integrated with a block.
