Abstract
A V-ribbed belt includes a compression rubber layer having a frictional power transmission surface that is covered with a fabric. The compression rubber layer includes an inner rubber layer in contact with the fabric and an outer rubber layer on an outer side of the inner rubber layer. The inner rubber layer is formed of a rubber composition having a Mooney Scorch minimum viscosity of 50 to 110 when measured at 125° C., and the outer rubber layer is formed of a rubber composition having a Mooney Scorch minimum viscosity of 70 to 130 when measured at 125° C.
