Abstract
PURPOSE: To make the strength of a V-groove uniform over the whole circumference of a pulley by forming a plurality of through-holes in the outer periphery of a circular metal plate as well as an annular bent portion around the outer peripheral edge, and by molding a plastic belt winding portion so that they are covered.
CONSTITUTION: A main body 1 made of a circular metal sheet is provided in its center with a shaft receiving hole 2 and as well formed in its outer periphery with a plurality of equally spaced through-holes 3 having the same diameter. Further, an annular bent portion 4 is formed at the outer peripheral edge of the main body 1 through a reducing process and is provided with a molded plastic belt winding portion 5. In this molding step, all through-holes 3 excepting some arranged in symetrical positions are covered with a mold plastic, thereby a V- groove 6 is formed around the outer periphery of the main body.
