されていることを特徴とする無段変速機用駆動ベルト。A carrier formed by stacking hoops in multiple layers, a main body portion having a tapered side surface, and a plurality of carrier grooves that are successively attached to the carrier so as to be movable in the circumferential direction of the carrier via the carrier grooves. The main body of the V block is wound around a pair of ■-shaped belt wheels, and the side surface of the main body of the V-block comes into contact with the drive surface forming the ■ groove of the ■-shaped belt wheels, thereby transmitting torque between the two ■-shaped belt wheels. A drive belt for a continuously variable transmission according to the present invention, wherein the carrier is composed of a welded hoop formed by welding both ends of a band-shaped metal except for the innermost layer hoop or several layers of hoops including this hoop. A drive belt for continuously variable transmissions featuring:
