PROBLEM TO BE SOLVED: To reduce the noise generated from a V-ribbed belt. SOLUTION: The V-ribbed belt 10 has a rib rubber layer 11. The rib rubber layer 11 has a plurality of V ribs extended in the longitudinal direction. Countless numbers of short fibers 20 are uniformly mixed in the rib rubber layer 11. The short fibers 20 are partially projected from a side face 16 of the V-rib 15. The tensile strength of the short fibers 20 is 8.6-16.2 cN/dtex. The rubber hardness of the rib rubber layer 11 is 84-91. COPYRIGHT: (C)2005,JPO&NCIPI |
