In addition, the process of arranging them at intervals, press-fitting resin into the cavity of the mold, and attaching with the press-fitted resin compresses the rubber sleeve of the tool in the thickness direction. The surroundings are wrapped around and cooled and solidified, thereby obtaining a coupling consisting of the fitting and the rubber sleeve compressed in the thickness direction, and a resin part that wraps and connects the fitting and the rubber sleeve for each fitting. It is characterized by this.
