A metal element (32) comprising an element main body part (34) and an element head part (36) on the radial inner and outer sides of right and left ring slots (35) to which a metal ring assembly (31) is press-fitted, respectively, the element main body part (34) and element head part (36) being allowed to be in contact with each other through inner and outer side contact surfaces (38, 39) formed on these two parts, respectively, wherein the width W2 of the outer contact surface (39) in contact with the inner side contact surface when the metal element (32) is located at the chord part of a metal belt is set large so as to prevent the metal element (32) from yawing, and the width W1 of the inner contact surface (38) in contact with the outer contact surface when the metal element (32) is located at a pulley winding part is set small so as to permit a yawing of the metal element (32), whereby an offsetting of a misalignment between a drive pulley (6) and a driven pulley (11), and the prevention of meandering of a metal belt (15) are made compatible with each other.
