抱合固定することが出来た。The convergence and fixing of the small-diameter pipe according to the present invention is performed as described above. Therefore, when a polypropylene resin dissolved at a high temperature is injected into a mold in which the small-diameter pipe is held in parallel, the small-diameter pipe is not fixed. Since the insertion portions in the molds 2, 2 'of the pipe 1 are roughened to an appropriate roughness, the injection pressure exerts an anchoring effect by cutting into the roughened portion of the small-diameter pipe 1. Since the solidified tube was solidified in this state, the small-diameter pipe 1 could be firmly conjugated and fixed by the polypropylene resin spacer 6a in a tightly adhered state.
