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.

An element of a transmission belt includes a pair of rocking edge portions with a convex surface, these are formed on one of a front face and a rear face to extend a part of the rocking edge portion over a pillar portion, and the rocking edge portions are spaced away from each other in a width direction; and a non-contact portion extended along a saddle surface in the width direction between the rocking edge portions, in non-contact with an adjacent element. S/A≥3.5 is satisfied, when a sum of widths of end portions of the rocking edge portions on an outer peripheral side of the transmission belt is set as “A”. A sum of surface areas of parts of the pillar portions on the outer peripheral side of the transmission belt is set as “S”.

Provided is a metal belt for a belt-driven continuously variable transmission in which metal elements are capable of keeping the compliance value small even when defamed. Each metal element of the metal belt includes a body portion located radially inward of metal rings, an ear portion located radially outward of the metal rings, and a neck portion sandwiched by the pair of metal rings and connecting the body portion and the ear portion. At least one of a front surface and a rear surface of the metal element has a recess at a center region in a right-left direction of the ear portion, and the depth of the recess is larger than the amount of curving in a front-rear direction of the ear portion.

A drive belt includes a hoop and multiple elements joined together in a loop by the hoop. Each element has an assembly space into which one end portion of the hoop is inserted during assembly. Each element is configured such that a first opening width, which is a distance between a first hook and a second hook, is less than a width of the hoop, and a second opening width, which is a distance between the second hook and a contact site where the one end portion of the hoop housed in the assembly space contacts a first pillar, is greater than the width of the hoop. The first hook and the second hook respectively include a first displacement-restriction surface and a second displacement-restriction surface each configured to restrict relative displacement between the element and the hoop by contacting a corresponding one of edges of the hoop.

In a pushbelt for a continuously variable transmission that includes at least one endless carrier and a number of transverse segments, which are mounted on the endless carrier. The transverse segments include a bearing surface that contacts the radial inside of the endless carrier, as well as a convexly curved tilting edge that is a part of a main body surface of the transverse segment. According to the present disclosure the convex curvature of the tilting edge extends both radially inward or below and radially outward or above the bearing surface, at least as seen in radial or height direction relative to the endless carrier.

In a transmission belt of a continuously variable transmission, a plurality of types of elements having different shapes is arrayed. A ratio of the numbers of the respective types of the elements in a string portion of the transmission belt is set so that, when first and second pulleys of the continuously variable transmission are misaligned, a total sum of deformation volumes of end portions of the elements on a side closer to a virtual plane in the element width direction is smaller than a total sum of deformation volumes of end portions of the elements on a side farther from the virtual plane. The virtual plane passes a center of a space between sheaves of the second pulley and is perpendicular to a rotating shaft of the second pulley.
