Abstract
A transmission belt is formed by a plurality of elements each having: a body portion including a saddle surface that contacts an inner peripheral surface of an endless ring and a pair of pillar portions that are extended outward in the 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 portion in the circumferential direction of the transmission belt and a second surface that is formed on the other side of the body portion in the circumferential direction of the transmission belt; and rocking edge portions 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 rocking edge portions 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. 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 edge portions are in the circumferential direction of the transmission belt.
