PROBLEM TO BE SOLVED: To improve, in a bearing with resin pulley including a resin pulley integrally molded on the outer circumference of an outer ring of a roll bearing by injection molding, the heat release property of the roll bearing while ensuring the rigidity of the resin pulley. SOLUTION: The bearing width of the roll bearing 11 is formed larger than a standard dimension (a dimension of bearing width regulated by JIS and set according to load), and the axial width of an inner diameter part of the resin pulley 21 is formed in the standard dimension. According to this, both end surfaces of the resin pulley 21 are located axially inside both end surfaces of the outer ring 13, and both end parts of end surface and outer diameter surface of the outer ring 13 can be exposed to improve the heat release property of the rolling bearing 11. Since the axial width of the inner diameter part of the resin pulley 21 is formed in the standard dimension, the rigidity of the resin pulley 21 can be ensured. COPYRIGHT: (C)2010,JPO&INPIT
