Claims

[Scope of utility model registration request]

A carrier formed by laminating a plurality of hoops, a main body part and a large number of blocks having a carrier groove provided on the upper part of the main body part, the carrier contacting surface of the carrier groove making frictional contact with the inner circumferential surface of the carrier. The (1) block is attached continuously in the circumferential direction of the carrier via the carrier groove, and (2) the inclined both sides of the block are frictionally engaged with the partially conical drive surfaces of a pair of V-shaped belt pulleys. A drive belt for a torque transmission device used in a torque transmission device, characterized in that the block (1) is provided on a carrier abutment member that integrally attaches the carrier contact surface portion of the carrier groove to the main body. drive belt.
