Abstract
A continuously variable transmission having a metal belt and pulleys is provided to effectively lubricate the pulley contact surfaces of a metal element of the belt of the transmission with lubricating oil supplied via a rotary shaft of the pulley. This makes it hard for a contaminant present in the lubricating oil to adhere to the metal element. When the saddle surface of the metal element is taken as a reference, the height h1 to the inner end in the radial direction of a pulley contact surface is set to be smaller than the height h2 to the inner end in the radial direction of the lateral middle part of an element main body. The inner end in the radial direction of the middle part of the element main body protrudes inwards in the radial direction by a distance d from the inner end in the radial direction of the opposite ends thereof. Lubricating oil supplied to the inner circumferential surface of the metal belt wrapped around the pulley, can be supplied smoothly from the lateral middle part of the metal element to the oppostie ends thereof by centrifugal force, thus effectively lubricating the pulley contact surface of the metal element and the V-face of the pulley.
