Abstract

PURPOSE: To extend life of the press mold as well as to ease up the condition of press punching by thinning the thickness of slit punching portion before press processing.
CONSTITUTION: Formation of a external cylindrical part 11 to rig and fix a V- groove part 1, a discoid part 12 to adsorb an armature, and an internal cylindrical part 14 to provide a positioning part 13 for positioning an outer race of a bearing by cutting-machining, and formation of a recess 16 which is wider than the slit 15 on the discoid part 12 by press processing before punching process of a slit 15 on the discoid part 12 by the press procedure minimize the thickness of the slit part 15 on the discoid part 12 less than the width of the slit 15.
