ABSTRACT:
A rubber part having a metal fitting in which the metal fitting and the rubber part are integrated through an anti-corrosion chemical film formed on a surface of the metal fitting. The anti-corrosion chemical film is a zirconium-based chemical film that is harmless to human body and environment, and is transformable following the squeeze of the metal fitting. The rubber part having a metal fitting is produced by the steps of: degreasing an outer peripheral surface of the metal fitting, subjecting the surface to shot blasting treatment, degreasing the treated surface, and water washing the treated surface; forming a zirconium-based chemical film on the treated surface; water washing and drying an outer peripheral surface of the zirconium-based chemical film; forming an adhesive layer on the outer peripheral surface of the zirconium-based chemical film; and integrating the rubber part on the outer peripheral surface of the adhesive layer.
