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.

Abstract: A transfer belt wound between a primary pulley and a secondary pulley of a continuously variable transmission, the transfer belt including: a plurality of elements, each of which has a body that includes a saddle surface and a pair of pillars that extend toward a radially outer side of the transfer belt from both sides of the saddle surface in a width direction; and a bind ring that binds the plurality of elements annularly with an inner peripheral surface of the bind ring contacting the saddle surface of each of the plurality of elements.

Abstract: A power transfer belt that includes a plurality of elements; and a ring that binds the plurality of elements annularly, wherein: the power transfer belt is wound in V grooves of a pair of pulleys of a continuously variable transmission to transfer power, the elements each have a saddle surface that contacts the ring, a pair of pillars that extend from both sides of the saddle surface in a width direction in a direction from an inner peripheral side toward an outer peripheral side of the ring, and a pair of side surfaces formed so as to extend away from each other from the inner peripheral side toward the outer peripheral side of the ring.

Abstract: A power transfer belt, where a peripheral length difference between an inner peripheral length of the retainer ring and an outer peripheral length of the outermost ring material is larger than a peripheral length difference between an outer peripheral length of the ring material on an inner side, of two of the ring materials which overlap each other, and an inner peripheral length of the ring material on an outer side,

Abstract: In an element of a power transfer belt to be wound around a primary pulley and a secondary pulley of a continuously variable transmission to transfer torque, the distance from a boundary line between a surface positioned on the outer peripheral side of the power transfer belt with respect to a rocking edge portion and the rocking edge portion to a saddle surface is determined from the slip amount due to micro slip which is relative slipping between the element and the primary pulley caused when the primary pulley pushes out the power transfer belt toward the secondary pulley, and the angular speed of the element and the angular speed of a ring in a range in which the power transfer belt is wound around the secondary pulley.
