PROBLEM TO BE SOLVED: To provide a resin pulley capable of improving heat radiation property by radiating heat generated in a bearing while the resin pulley rotates into the atmosphere quickly. SOLUTION: This resin pulley has a pulley main body 2, a press-fitting part 4 which is provided in a central part of the pulley main body 2 and in which the bearing 3 is press-fitted, and a rib part 5 provided radially between an inner side of the pulley main body 2 and the press-fitting part 4. A metallic heat radiation part 10 coming into contact with the bearing 3 and the outside air is integrally provided in the rib part 5. Consequently, since a radial heat radiation part 11 rotates and comes into contact with comparatively large quantity of outside air to radiate heat easily while the resin pulley 1 rotates, heat generated in the bearing 3 is transmitted to the heat radiation part 11 and is radiated into the atmosphere.
