A chain is formed by coupling chain elements including plate-shape links arranged in the width direction of the chain and pins (42) extending through the links in the width direction of the chain, in the circumferential direction of the chain. The pin (42) is clamped between two opposing substantially conical surfaces 24 and 26 of a pulley (12). The deformation ratio of the pin length when the pin is clamped by the pulley is set to be 1.3 x 10 -6 (1/N) or greater. The deformation ratio of the pin length is represented by (deformation ratio) = ”L/(F x L), wherein L indicates a length of the pin, F indicates a load applied to the pin, and ”L indicates a deformation quantity. Thus, noise of a chain-type continuously variable transmission in the frequency band of 3 to 5 kHz can be reduced. |
