特徴とするベルト駆動装置。[Claims for Utility Model Registration] A belt with a V-shaped cross section is wound around a pulley that is driven by an engine and whose rotational angular velocity periodically fluctuates as the engine's torque fluctuates. In a belt drive device in which engine power is transmitted by contact between the side surface and the inner surface of the V-shaped groove of the pulley, from the center point of the belt wrapping angle of the pulley when the piston of the engine is at compression top dead center. A belt drive device characterized in that a region with reduced frictional resistance against the belt is provided on the inner surface of the V-shaped groove of the pulley at a position delayed by approximately 90 degrees with respect to the crank angle.
