摘要：
A pair of pulleys for a belt-and-pulley type continuously variable transmission wherein the pulleys are connected by a transmission belt such that the belt is partially in contact with contact surfaces of the pulleys. At least one of the pair of pulleys has a contact surface which has a plurality of raised and recessed portions that are spaced apart from each other at irregular angular intervals in a circumferential direction of the pulley.
