A surface roughness is formed in a portion of a surface of the metal part to which the rubber is adhered, and the surface roughness is transcribed from a mold to the metal part by previously providing with a surface roughness in the mold. A magnitude of the surface roughness is preferably set to be 10 μm or more and less than 60 μm.
