In a metal part in which a rubber is adhered to a portion or the whole of a surface thereof, and a surface treating method of the metal part to improve adhesive property between the metal and the rubber, to make it easy to form a surface roughness in a portion of a metal part, and to achieve an improvement in the surface roughness and mold maintenance property, a reduction of working cost, and a reduction of man hour. A surface roughness for increasing adhesive property between the metal and the rubber is formed in a portion of the metal part to which the rubber is adhered, and the surface roughness is transcribed from a mold to the metal part by 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.
A surface treating method of a metal part in order to form a surface roughness for increasing an adhesive property between the metal part and a rubber on a portion, to which the rubber is adhered, in a surface of the metal part, comprising the steps of:
A method to prevent two or more metal parts from binding to each other after the metal parts are simultaneously dipped in an adhesive agent solution and said adhesive agent solution is applied to the metal parts, comprising the steps of:
