PURPOSE:To make both of a metal part and a plastic member rotatable to each other and to enable the integral molding of both parts, by bringing th region to be connected of the metal part to a slip-out preventing structure and applying a release agent to said structural part before molding plastic at the region including said structural part. CONSTITUTION:In order to bring the end part to be connected of a rod member 10 to a slip-out preventing structure, for example, a ring shaped cut groove 16 is formed to said end part 14. Subsequently, a release agent 18 is applied to the surface of the entire peripheral edge of the end part 14 of the rod member 10 and a plastic member 12 if formed at the release agent applied region by injection molding or other proper means so as to obtain a desired shape. An extremely narrow gap is generated at the connection regions of both member 10, 12 by said release agent and both members 10, 12 can rotate to each other but is brought to an integral structure generating no separation. Therefore, a product, wherein the gap of a revolving part is extremely precise, can be easily and certainly obtained in an extremely simply manner.
