Abstract: PROBLEM TO BE SOLVED: To prevent a V-pulley from being slipped on a pulley even under watered environment. SOLUTION: This pulley comprises a communication hole 130 for communicating the bottom parts 121 of V-grooves 120 with the side surface part 112 of a pulley body 110, and a groove part 131 extending to the bottom parts 121 of the V-grooves 120 provided in the sloped side surfaces 122 of the V-grooves 120. Thus, the water adhered to the inside of the V-grooves 120 can be drained to the outside of the pulley 100 through the communication hole 130. Therefore, the V-belt 200 can be prevented from being slipped on the pulley even in watered environment.
