Transmission belt

A transmission belt that is wound around a primary pulley and a secondary pulley of a continuously variable transmission, the transmission belt comprising:

• an endless ring having a ring shape with no ends;
• and
• a plurality of elements, each of which has:
• a body including a saddle surface that contacts an inner peripheral surface of the endless ring and a pair of pillars that are extended outward in a radial direction of the transmission belt from both lateral sides of the saddle surface,
• a first surface that is formed on one side of the body in a circumferential direction of the transmission belt and a second surface that is formed on the other side of the body in the circumferential direction of the transmission belt, and
• rocking edges that are formed at both lateral ends of the first surface so as to be separated from each other and that act as a fulcrum when adjacent ones of the elements contact each other and rotate relative to each other, the plurality of elements being stacked on each other and supported by the endless ring so as to be arranged in the ring shape, wherein
• the rocking edges are formed by a curved surface so as to have a width from a position outside the saddle surface to a position inside the saddle surface in the radial direction of the transmission belt, and
• a portion connecting the first surface and the saddle surface is formed so as to be located closer to the second surface than the rocking edges are in the circumferential direction of the transmission belt.
