ABSTRACT:
A pulley adapted to be press-fit on a driving shaft has projections having vertex portions with flat surfaces formed on an inner peripheral surface which is defined by a center hole of the pulley. The flat surfaces of the projections make pressing contact with an outer peripheral surface of the driving shaft at a band-shaped contact area (or surface) extending spirally or concentrically along a longitudinal direction of the pulley.
