Abstract
A frictional transmission belt looped over V-ribbed pulleys for torque transmission. The V-ribbed pulleys are coated with anticorrosive paint prior to shipment of an automobile. A surface-active layer made of a surfactant is formed on surfaces of ribs on a belt body With the existence of the surface-active layer, generation of an abnormal sound due to stick slip is suppressed even when the anticorrosion paint has not come off, without impairing the belt transmission capability.
