Abstract
A V belt (1; 201) for power transmission to be stretched over a driving pulley (100) and a driven pulley to effect power transmission therebetween, the V belt comprising a looped metallic belt (2), a plurality of V-shaped metallic blocks (3; 203) fitted on the metallic belt in a continuous manner along the length of the metallic belt, and a plurality of stoppers (5; 75) each respectively applied to one of the V-shaped blocks to cooperate with a concave groove (3b; 203b) of the V-shaped block so as to surround the metallic belt. At least a part (5d; 75d) of a base portion (5a; 75a) of the stopper is curved in a radial direction of the V belt to permit a resilient uniform opening of both side portions (5b; 75b) thereof in lateral directions (Y). The V belt further comprises a plurality of rollers (4) each respectively disposed between neighboring two of the V-shaped blocks; the V-shaped blocks include a number of V-shaped blocks (3x, 3y) falling into at least two types having their minimum longitudinal thicknesses (l.sub.2, l.sub.3) different from each other; and V-shaped blocks (3y) of at least either type each have a marking (3i, 3j; 3k) visually identifiable from outside of the V belt. The V belt (201) further includes a plurality of rollers (4) disposed between the V-shaped blocks, respectively, and the V-shaped blocks (3, 203) include a number of V-shaped blocks (203) of another type each having at either side of the V belt a convex part (203e) playing the role of a roller.
