Abstract
A transmission belt is formed by annularly arranging elements including a plate-shaped first element and a plate-shaped second element, and annularly connecting the elements using a ring. The first element includes a first edge surface on which a burr is formed when the first element is formed by a press operation. The second element includes a second edge surface on which a burr is formed when the second element is formed by the press operation. The first and second edge surfaces face in directions opposite to each other in a direction in which the elements are arranged. The first edge surface includes a first rocking edge that contacts the element adjacent to the first element when the elements are arranged in an arc. The second edge surface includes a second rocking edge that contacts the element adjacent to the second element when the elements are arranged in the arc.
