Abstract
PURPOSE:To promote the miniaturization, weight lightness and the improvement of reliability in the mechanical strength by integrally forming a web with a rim by a metal material folded in its peripheral part while increasing a plate thickness of the rim so as to be larger than the plate thickness of the web. CONSTITUTION:A disk-shaped metal thin plate 10 forms its central part by drawing into a housing 7, being rotated clamped by a jig 11, and pressing a thickness increasing bending roller 12 to a peripheral part 10b performing thickness increasing bending work next pressing a preliminary molding roller 14, flanges 5, 6 are formed. Subsequently, a finish molding roller 15 is pressed forming a poly-V groove 2a by rolling on the peripheral part 10b serving as a rim 2, and a pulley 1 is manufactured. This pulley 1 increases the thickness of the rim 2 without generating a two-fold part in a connection part 4 between the rim 2 and a web 3. Thus promoting the miniaturization and the lightness of weight, while even in the point of mechanical strength, the reliability can be sufficiently enhanced.
