ABSTRACT:
A composite plastic and metal pulley intended primarily for use with an endless drive belt for vehicle accessories, particularly an alternator. The pulley is formed by a hollow cylindrical-shaped molded plastic member having a series of outwardly opening V-shaped belt-receiving grooves on the outer surface thereof. A flat disc-shaped metal member is mounted within the central bore of the plastic member perpendicular to the longitudinal axis thereof. The outer edge of the metal disc is scalloped and is embedded firmly within the plastic to prevent rotation of the disc with respect to the plastic member. A central opening is formed in the disc for mounting the pulley on the extended end of the alternator shaft.
