Claims

[Scope of utility model registration request]

The carrier includes a carrier formed by stacking endless hoops in multiple layers, a main body portion and a carrier groove formed on the upper part of the main body portion and having a hoop contact surface, and is movable in the circumferential direction of the carrier via the carrier groove. It consists of a large number of ■ blocks that are successively attached to the carrier, and is wrapped around a pair of ■ type belt wheels, so that the tapered sides of the ■ blocks form a partially conical shape that forms the V groove of the ■ type belt wheel. A drive belt for a continuously variable transmission, which transmits torque between both type belt wheels by contacting a surface, and has a structure in which the carrier does not move as the blocks move during torque transmission, and wherein the carrier is in contact with the hoop of each of the blocks. The surface is formed into a planar shape, and between this hoop contact surface and the innermost hoop of the carrier, a large number of needle rollers are arranged so as to be rotatable at a predetermined pitch in the circumferential direction and protrude from the inner and outer peripheral surfaces. A drive belt for a continuously variable transmission characterized by interposing an endless flexible member.
