    • PURPOSE:To surely clamp a part whose holding part is smaller compared to the size of a tube and to hold sealing of the case of pouring fluid to a clamp part by providing a regulation member regulating the expansion of the tube in the desired range inside the tube expansion space. CONSTITUTION:The both ends of a cylindrical tube 2 are fitted to a base body 1 both ends, the expanded face of the tube 2 is made at the inner side of the base body 1, a passage 3 through which a fluid A is poured to the base body 1 is formed, the fitting of the tube 2 is performed by calking rings 4, 5 and to a flange like part 1A an expansion regulating member 6 regulating the expansion of the tube 2 is fitted. The flange like part 1A is fitted by sealing to a container 7, the fluid B flowed into the container 7 is flowed into the part 10 whose part has a flange 11 and capable of holding by the tube 2 is short and the gap DELTAt between the upper end of the regulation member 6 and the lower end of the part 10 is made almost zero. In order to clamp the part 10 a fluid a is poured into the tube 2 by specified pressure, the sealing property between the tube 2 and part 10 is secured and due to the expansion face of the tube 2 not coming into contact with the part 10 by the regulation member 6 not jamming the passage inside the part 10 the fluid B comes into the part 10.
