Abstract

PURPOSE:To enable the external surface of a tubular member to be certainly supported, by inserting an elastic tubular member and a hollow unit into a branch retaining tube made of plastics, and by expanding the hollow unit and shrinking the diameter of the retaining tube, to manufacture a branch tube. CONSTITUTION:Into a branch retaining tube 1 made of plastics, a tubular member 2 having rubber-like elasticity is inserted. In this case, the ends of the tubular member 2 are set extended from the retaining tube 1. After that, into the tubular member 2, a hollow unit 3 is inserted, and the retaining tube 1 is heated to be softened. In this state, pressure is applied into the hollow unit 3 to expand it, and the diameter of the tubular member 2 is enlarged. At the same time, the retaining tube 1 is cooled to be solidified, and the internal surface of the retaining tube 1 and the external surface of the tubular member 2 are permitted to certainly come in contact with each other. Then, the extra length sections of the end sections of the tubular member 2 are folded back to form engaging sections 2b, and finally, the hollow unit 3 is contrived to be removed from.
