Abstract
Protrusions formed on an inner peripheral surface of at least an innermost metal ring of a belt for a continuously variable transmission are initially worn. An average contact widthof the protrusions, measured in a direction perpendicular to a direction of travel of the metal ring, is equal to or less than 16 μm. The development of pitching at a top of the protrusion in a depthwise direction is inhibited. Shallow pitching is eliminated due to the contact between the protrusion and a metal element, which prevents the generation of cracks. When the metal ring and the metal element are conformed to each other, the average Hertz's surface pressure is lowered, whereby the pitching is difficult to occur. Also, the top of the protrusion is worn, leading to an improved surface roughness, whereby the lubrication is enhanced, resulting in an enhancement of metal ring durability.
