Belt for continuously variable transmission

Abstract

Each of metal elements 32 includes an element body portion 34 and an element head portion 36 on radially inner and outer sides of left and right ring slots 35 into which metal ring assemblies 31 are fitted, respectively. The metal elements 32 can be brought into contact with one another at inner contact surfaces 38 and outer contact surfaces 39 each of which are formed on the element body portion 34 and the element head portion 36, respectively. The width W2 of each of the outer contact surfaces 39 which is in contact with each other when the metal elements 32 are in a chord portion of the metal belt, is set at a large value so as to prevent the yawing of the metal elements 32, and the width W1 of each of the inner contact surfaces 38 which is in contact with each other when the metal elements 32 are in a pulley-wound zone, is set at a small value so as to permit the yawing of the metal elements 32, whereby the absorption of a misalignment between a drive pulley 6 and a driven pulley 11 and the prevention of the zigzag movement of a metal belt 15 can be reconciled.
