Abstract
In a metal belt for a continuously variable transmission having a saddle face of a metal element and a rocking edge positioned at substantially the same position in the radial direction, a rocking edge is provided at a radially outer end of a front face of a body part, the rocking edge being a fulcrum for pitching of the metal element of the metal belt which is wound around a drive pulley and a driven pulley and transmits a driving force between the two pulleys, and a recess is provided extending from a front face of a neck part to a front face of the body part. Thus, it is possible to minimize a space created between the front and rear metal elements and reduce the bending stress applied to the metal elements, thereby minimizing degradation of the power transmission efficiency.
