点にある。However, the transmission belt, which is stretched strongly, slides in the axial direction of the pulley along with the movement of the movable pulley during a gear shifting operation, so that the transmission belt is slightly twisted and Stress is concentrated on the elastic belt in a tensioned state that connects the matching transmission pieces. As a result, there is a possibility that the elastic belt, which is the connecting portion of the transmission piece, may be broken during long-term use, and there is room for improvement in terms of durability. An object of the present invention is to provide a power transmission belt that reduces the stress load on the elastic belt and, by extension, has improved durability.
