なかつた。Description of the Prior Art Conventionally, caulking methods, welding, and the like have been used to connect, for example, two pipes. However, the caulking method has drawbacks such as deformation of the objects to be connected due to the caulking process and difficulty in re-separation since it utilizes permanent deformation of the metal. Furthermore, in the case of welding, there are disadvantages in that the objects to be connected are exposed to high heat and are therefore easily deformed and difficult to separate again. In addition, welding cannot be performed when the objects to be connected are made of organic substances or have organic substances on their surfaces, and it is difficult to connect materials with poor weldability or dissimilar materials. There were also some drawbacks. Furthermore, there were also restrictions on where welding could be performed. In other words, connections could only be made where welding equipment was available or where there was space for welding work.

３を加工するのが困難であつた。 As described above, conventional pipe connection methods have many drawbacks. On the other hand, in recent years, a method of connecting two pipes using a joint made of a shape memory alloy has been developed. As shown in Fig. 1, pipes 1 and 2 to be connected are butted together, and a pipe-shaped shape memory alloy member 3 whose transformation temperature is set to, for example, -120°C is placed in liquid nitrogen with the diameter of the pipes 1 and 2. After expanding the pipe to have a larger diameter, the pipe is inserted and positioned around the joint of the pipes 1 and 2. next,
The shape memory alloy member 3 is heated and returned to room temperature, and the pipe 1 and the pipe 2 are connected by the heat recovery force. However, even in this method,
There was a problem in that the shape memory alloy member 3 had to be prepared depending on the diameters of the pipes 1 and 2. This is because the amount of deformation of the shape memory alloy member 3 due to thermal recovery is only about 4%.
Therefore, to connect pipes of various diameters,
Shape memory alloy members 3 of various diameters are required. Moreover, when using this shape memory alloy member 3,
There is also the problem that the connection is difficult unless the diameters of the pipes 1 and 2 are the same and the surfaces of the end faces of the connecting portions are not flat. Furthermore, shape memory alloy member 3
Another problem was that expanding the pipe required large-scale equipment and extremely large external forces. Furthermore, shape memory alloys are generally difficult to process, making it difficult to process the shape memory alloy member 3.
