A power transmission V-belt includes a tension member, an adhesion rubber layer in which at least part of the tension member is embedded, and a tension rubber layer and a compression rubber layer stacked via the adhesion rubber layer. A rubber hardness of the tension rubber layer is smaller than a rubber hardness of the compression rubber layer. In the adhesion rubber layer, a rubber hardness on a tension rubber layer side relative to the tension member is smaller than a rubber hardness on a compression rubber layer side. |
