Abstract
The clutch hub includes a sheet-metal hub member which has an axial member projected from the center of its plate surface, and also includes an annular armature which is fixed to an outer peripheral portion of the axial member. First mounting the axial member of the clutch hub downward on a support member and thereby elastically supporting the end surface of the armature by the support member; holding the axial member of the clutch hub using a chuck; locating a fixing member just under a portion of a maximum runout portion of an inner hub; contacting a cylindrical end surface of a pressing member with an upper surface of the inner hub using pressure; and plastically deforming the inner hub by a pressing force of the pressing member using the locating portion of the fixing member as a fulcrum, which thereby corrects an inclination of the axial member.
