Abstract
A pulley body has a first flange and a fitting protrusion. The flange body has a second flange and a fitting recess fitted to the fitting protrusion. The fitting recess has an inner surface including, in a radially inward direction, a first inclined surface inclined so as to approach the first flange, as extending in the radially inward direction. The fitting protrusion has a distal end surface including, in the radially inward direction, a second inclined surface facing the first inclined surface. The flange body has an outer peripheral surface that faces an inner peripheral surface of the pulley body, and has a protrusion which continues in a circumferential direction with no end. A region including an annular-shaped area between the first and second inclined surfaces includes a joint portion of a molten resin.
