A generally disk-shaped flange plate is releasably attached to the other end of the winding body by locking tabs formed on the winding body which cooperate with apertures formed in the flange plate. Typically, the pulley body is formed of a nylon material and the flange plate is formed of steel. The winding body includes an internal wall and an aperture is formed in the wall and another aperture is formed in the flange plate for rotatably mounting the pulley on a supporting shaft. A coil spring has one end attached to the shaft and the other end attached to the winding body for automatically rewinding the extension cord.
