Abstract
A V-belt is mounted on a first fixed conical plate and second fixed conical plate of a lower unit, and an upper unit is made to descend. A first movable conical plate and second movable conical plate are installed in the upper unit, and the V-belt is gripped between the fixed conical plates and movable conical plates. When a rotary actuator of the lower unit draws a drawbar which extends below the movable conical plate downwards, a predetermined pressure is applied to the V-belt. The first movable conical plate and first fixed conical plate are rotated in this state to drive the V-belt, and a noise test is performed.
