Abstract

PURPOSE:To shorten the process and to improve the yield by forming one of the V-grooves simultaneously with the molding of the annular member having the C-shaped cross-section while splitting the outside cylindrical section of said annular section through the undercutting, thus forming the other V-groove. CONSTITUTION:Rotor 1c is formed in such configuration in which the portion acting as frictional face 6 and another portion P1 acting as the one side wall of V-groove P are integrally molded on one end of a roughly cylindrical body provided with annular groove of C-shaped cross-section, and cylinder Lp of the external cylindrical portion is added with the volume equivalent to the space for composing portion P2 which acts as the other side wall of V-groove P. After this rotor 1c is fabricated through trimming to 1d, the other side wall P2 of V-groove P is contracted through undercutting into material 1e. And wall P2 of V-groove subjected to trimming is molded into the predetermined configuration, while being fixed by the metal mold which is provide for the purpose of preventing deformation of both internal and external cylindrical portion Lp, Sp and the end face portion acting as frictional face 6.
