The surface of the toothed rubber layer, on which the teeth are formed, is covered with a cover fabric. A back rubber layer is integrally applied to the other surface of the toothed rubber layer. A plurality of cord elements is disposed across a width of the belt and is intervened between the toothed rubber layer and the back layer in such a manner that a portion of each cord element is embedded in the toothed rubber layer, and the remaining portion thereof is embedded in the back rubber layer. The short fibers are entirely distributed in the toothed rubber layer and are regularly oriented.
