    摘要： A V-ribbed belt includes a plurality of V-rib portions extending along a longitudinal direction of the belt and in parallel with one another, and a compression rubber layer including a frictional power transmission face at least a part of which can come into contact with a V-rib groove portion of a pulley. The frictional power transmission face of the compression rubber layer is formed from a vulcanizate of a rubber composition containing a rubber component and a noise suppression improver. A difference (Rp−Rb) between a curvature radius Rp of a rib top end of the pulley and a curvature radius Rb of a rib bottom portion of the V-ribbed belt is −0.08 to 0.08 mm.

    摘要： In a V-ribbed belt provided with a compressed rubber layer having V-ribbed portions extending parallel to one another in a belt longitudinal direction, and having a friction transmission surface at least a portion of which is capable of coming into contact with a V-ribbed groove portion of a pulley, the friction transmission surface of the compressed rubber layer is formed from a rubber composition vulcanizate including a rubber component and a sound generation resistance improving agent. A difference between a radius of curvature of a rib distal end portion of the pulley and a radius of curvature of a rib bottom portion of the belt is adjusted to be −0.08-0.08 mm. The radius of curvature of the rib bottom portion may be approximately 0.1-0.5 mm. The radius of curvature difference may be −0.05-0.05 mm. The pulley may include a pulley having an outer diameter at most equal to 65 mm.

    摘要： The present invention relates to a frictional power transmission belt containing an extensible layer to form a belt back surface, a compressive layer formed on one surface of the extensible layer and having a power transmission surface at least a part of which can be in contact with pulleys, and a tension member embedded between the extensible layer and the compressive layer along a belt length direction, in which at least the compressive layer is formed of a rubber composition containing a polymer component, short fibers and a surfactant and in which the short fibers contain at least short fibers of water-absorbing fibers.
