Abstract
A first body is formed from a first cylindrical member. The first body includes a restricted portion which extends circumferentially along the first body and has an inner diameter smaller than that of the first cylindrical member, a V-shaped groove on the outer surface of the restricted portion, opposite cylindrical end portions which have a diameter substantially equal to that of the first cylindrical member, and a pair of annular connecting portions which connect the end portions to the respective ends of the restricted portion. Further, a second body is formed from a second cylindrical member which has a diameter smaller than that of the first cylindrical member. The second body includes a cylindrical portion which has a diameter substantially equal to that of the second cylindrical member, a flange portion connected to the cylindrical portion and having a diameter larger than the inner diameter of one end portion of the first body, and an annular groove between the flange portion and the cylindrical portion. The flange portion includes an inclined surface along the periphery of the flange portion. The first and second bodies are assembled by fitting the flange portion of the second body into one of the end portions of the first body. A non-magnetic material is filled within the annular groove and a space between the inclined surface of the flange portion of the second body and the end portion of the first body. The outer end of the assembly is machined to provide a friction surface and to expose the non-magnetic material on the friction surface to form a rotor for an electromagnetic clutch.
