Abstract

A continuously variable transmission includes a primary pulley, a secondary pulley, a metal belt wound around the primary pulley and the secondary pulley, and a controller. The metal belt includes a ring and a plurality of elements. The elements have respective receiving portions opening in a radial direction of the belt and receive the ring in the receiving portions. The controller executes a preliminary determined falling-off countermeasure control of the element when the end play larger than the predetermined length is detected to be generated or the continuously variable transmission is detected to be under the operation condition in which the end plays concentrate.
