A metal V-belt type continuously variable transmission in which the length of a side of an element contacting with a V-face of a pulley is shortened to increase a ratio range. If the element side length of a metal element is represented by L, the angle of the V-face of the pulley is represented by .alpha., and the hertz surface pressure between the pulley and the metal element is represented by .sigma..sub.H, the following relation is established: L .varies. sin .alpha./.sigma..sub.H.sup.2. When the hertz surface pressure .sigma..sub.H is determined to be between an upper limit value defined by the wear durability of the metal element and a lower limit value defined by the limit tensile force of an endless belt, the element side length L can be decreased by decreasing the angle of the V-face of the pulley. Thus, the distance through which the metal element can be moved radially of the pulley is increased to increase the ratio range.
A metal V-belt type continuously variable transmission, comprising an endless belt which has a large number of metal elements mounted on a metal ring and which is wrapped around a pair of pulleys, an inclination angle .alpha. of a V-groove in each said pulley being set in a range of:
