Claims

[Scope of utility model registration request]

A pair of carriers formed by laminating endless metal bands, a main body portion having tapered side surfaces, a neck portion provided on the upper surface of the main body portion, and a guide portion provided on the upper surface of the neck portion, and the neck portion consisting of a number of V-blocks that are slidably and consecutively attached to the carrier via a pair of carrier grooves formed on the left and right sides of the carrier, and A drive belt for a continuously variable transmission in which a concave continuous part is formed at the connecting part and is wound around a pair of ■-shaped belt wheels, the length of the carrier sliding surface of the carrier groove being asymmetrical between the left and right sides. A drive belt for a continuously variable transmission characterized by having at least two types of formed blocks.
