Friction drive belt and manufacturing method therefor
In order to allow a friction drive belt to have an effect of reducing slip noise produced between the belt and pulleys for a long period even when the belt gets wet with water or suffers from wearing out, a V-ribbed belt B as the friction drive belt includes a belt body 10 made of a rubber composition and configured to be wrapped around the pulleys to transmit power. The surfaces of V-shaped ribs 15 serving as a pulley contact-side surface of the belt body 10 are covered with a fabric layer 16 which is integrated with the surfaces of V-shaped ribs 15, and the fabric layer 16 retains powder 17 embedded between fibers of the fabric layer 16 and integrally stuck.
