A plate link chain for a continuously variable transmission of a motor vehicle is provided. The plate link chain includes a plurality of link plates arranged parallel to a running direction of the plate link chain and each link plate includes an aperture formed therein. A plurality of pressure pieces are oriented perpendicular to the running direction and arranged in pairs to be received in the apertures of the link plates to form two joints in each link plate. The two joints in each link plate are supported by arcuate outer sections of the pressure pieces.

An element for a transmission belt that is wound around a primary pulley and a secondary pulley of a continuously variable transmission includes: a trunk portion having a saddle surface that is in contact with a ring of the transmission belt; and a pair of pillar portions extending from the trunk portion so as to be positioned on both sides of the saddle surface in a width direction. The saddle surface is a convex surface that is formed by an elliptic arc and satisfies b/a0.015 when a long diameter of the elliptic arc is regarded as a and a short diameter of the elliptic arc is regarded as b. In this way, it is possible to optimize the stress distribution of the ring that is in contact with the saddle surface and improve the durability of the ring and the transmission belt.

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.
