A plurality of pipe members for supplying fluid are aligned and fixed to a connecting plate having engaging portions for the pipe members arranged at a plurality of positions in the longitudinal direction thereof, and a frame body using these pipe members as an aggregate is formed. After fixing the mounting seat to the outer surface of the frame,
It is characterized in that a mold is set around the frame and resin is injected into the frame, and after curing, the seat surface of the mounting seat is processed.
