Abstract
In a belt for a continuously variable transmission, a first clearance CL is defined between a projection and a recess formed on front and rear surfaces of a metal element, and a second clearance CLy is defined between an upper surface of a metal ring assembly and a lower ear surface of the metal element. By setting a relation, CLY>CL ensures, that when the metal element has been pitched, the projection and the recess can be first brought into contact with each other, thereby preventing a reduction in durability of the metal ring assembly. If the thickness of the metal ring assembly is represented by T , and the vertical opening of the ring slot is represented by D, when the value of D/T exceeds 11/8, the power transmitting efficiency is reduced. Therefore, the reduction in power transmitting efficiency can be prevented while maintaining durability of metal ring assembly by setting D/T at a smaller value than 11/8.
