Abstract
A V-ribbed belt having a rib rubber layer which includes a plurality of ribs extending under a tension member layer of a power transmission belt along the longitudinal direction of the belt. Short fibers are mixed in the ribs. The direction of orientation of the short fibers is near the longitudinal direction of the belt near the tension member layer and gradually changed toward near the vertical direction of the belt near the rib tops. Through the above arrangement, endurance to the shearing stress can be improved and flexibility is also maintained and consequently, endurance to rib chipping off is improved.
