Abstract

A bearing with a resin pulley, in which heat of the bearing is reliably radiated and the resin pulley is reliably prevented from being axially displaced. An outer ring (2) of the bearing has flanges (2a) arranged on opposite ends of the outer diameter surface of the outer ring (2), and the flanges (2a) project to the outer diameter side so as to radially expand end surfaces (S) of the outer ring (2). The resin pulley (4) is integrated with the bearing so as to expose the entire radially expanded end surfaces (S) of the outer ring (2). The end surfaces (S), which are not covered by the resin, function as wide heat radiation surfaces to secure heat radiation ability of the bearing. Further, the flanges (2a) projecting from the opposite ends of the outer diameter surface of the outer ring (2) prevent axial displacement of the resin pulley (4).
