PURPOSE:To obtain a long life, by forming a holding elastic material layer b short fiber contained rubber, consisting of chloroprene rubber, reinforcing filler, metal oxide vulcanizing agent, bismaleimide and aramide short fiber, and arranging the aramide short fiber in the width direction of a belt. CONSTITUTION:A V-belt 1 provides holding elastic material layer 4, 5 to be arranged in the upper and the bottom of an adhesive elastic material layer 3 embedding cords 2. The holding elastic material layer is formed by short fiber contained rubber, which adds a reinforcing filler, metal oxide vulcanizing agent, bismaleamide and aramide short fiber to chloroprene rubber, and the aramide short fiber is arranged in the width direction of the belt. Consequently, the belt, providing large elastic modulus in the linear direction, enables high torque to be transmitted further a long life to be obtained.
