実にタンク20に接続される。Next, the procedure for connecting the hose 10 to the tank 20 will be described with reference to FIGS. 1 (a) and 1 (b). (1) Preparation stage [See Fig. 1 (a)]. The inner cylinder 1 taken out from the dewar containing liquid air is mounted in a form in which the main body portion 2 is inserted into the inner cylinder connection port 21 on the tank 20 side. Since the outer diameter of the body 2 of the inner cylinder 1 is smaller than the inner diameter d 1 of the inner cylinder connection port 21, the body 2 is loosely fitted into the inner cylinder connection port 21 of the tank 20. Only the flange part 3 for posture control remains in the tank 20. ． The hose 10 is connected to the outer peripheral surface of the main body 2 exposed from the inner cylinder connection port 21 on the tank 20 side. The inner diameter dimension d 11 of this hose 10 is almost equal to the inner diameter dimension d 1 of the inner cylinder connection port 21, but the outer diameter dimension of the main body portion 2 on the inner cylinder 1 side is reduced by the above-mentioned processing, so this is easily desired. Can be positioned in position. ． The outer cylinder 5 taken out from the dewar containing liquid air is positioned at a position covering the outer peripheral surface of the hose 10. The outer cylinder 5 has the inner diameter dimension D which is the outer diameter dimension D of the hose 10 by the above processing.
Since it is expanded slightly in the radial direction from 11, it can be positioned at the desired position without resistance. (2) Mounting stage [see FIG. 1 (b)]. The outer cylinder 5 and the inner cylinder 1 are heated by sending hot air to the outer peripheral surface of the outer cylinder 5. Other heating methods include, for example, a method of heating them entirely using a vapor tank, but this heating method is not specified. ． This heating causes the inner cylinder 1 to move in the radial direction (← ・ → direction).
The diameter thereof is enlarged so that the main body portion 2 comes into close contact with the inner surface of the inner cylinder connection port 21 provided on the tank 20 side. At the same time, the outer cylinder 5 is contracted in the radial direction (→ · ← direction) by this heating so as to come into close contact with the hose 10 inserted in the inner cylinder 1 and press the hose 10 against the inner cylinder 1. The diameter expansion phenomenon of the inner cylinder 1 and the diameter reduction phenomenon of the outer cylinder 5 are due to the shape memory effect. ． The hose 10 is formed by pressing the inner diameter surface and the outer diameter surface of the inner cylinder 1 whose diameter is enlarged and the main body 2 is brought into close contact with the inner cylinder connection port 21 and the outer cylinder 5 whose diameter is reduced. Securely connected to tank 20.

Since the hose connecting portion is constituted by the cylinder 5, the work of connecting the hose 10 to the tank 20 is significantly efficient. In particular, since this hose connection mechanism can easily control the change in the diameter of the outer cylinder 5 (this control is performed at the stage of storing the shape in the outer cylinder 5), an obstacle due to over-tightening the hose 10 (tightening the hose 10). No obstacles such as passing and damaging it will occur.
