PROBLEM TO BE SOLVED: To provide a resin-made pulley with a bearing which can improve creep resistance even in a sever condition of a high belt load and a high rotation speed.SOLUTION: A wholly annular-shaped metal-made annular member 21 is pressure-inserted into an outside diameter face 3c of an outer ring 3, a resin-made pulley 15 is integrally molded around the metal-made annular member 21, the metal-made annular member 21 is composed of a hollow fitting part 23 which is fit to the outside diameter face 3c of the outer ring 3 by pressure-insertion, and a disc part 29 which is integrally erected from the fitting part 23 to a vertical direction, and a plurality of holes 31 which are formed at the bearing 1 in an axial direction are formed at the disc part 29 in a circumferential direction.SELECTED DRAWING: Figure 2 |
