Abstract
A pulley includes a radial rolling bearing and a pulley main body which are integrated to each other by an insert molding method. Therefore, a metal insert member is not required between the resin pulley main body and the radial rolling bearing, thereby reducing production cost of the pulley. Further, an axial dimension of an outer ring of the radial rolling bearing is set larger than an axial dimension of an inner ring thereof, so that a contact area between the radial rolling bearing and the pulley main body is increased. Therefore, a connection strength between the radial rolling bearing and the pulley main body is increased, and a surface area of the radial rolling bearing is increased, thereby improving heat radiation performance of the radial rolling bearing.
