PROBLEM TO BE SOLVED: To provide a tube for liquid transfer having a high pressure resistance and deformable and recoverable easily. SOLUTION: This tube 10 comprises a metal hollow tube 11 made of a shape memory alloy and a solid elastic body 12 inserted into the metal hollow tube 11. A fluid flows in a ring-like space 13 formed between the solid elastic body 12 and the metal hollow tube 11. The solid elastic body 12 is easily deformed by an external force from the projecting part 32 of a rotary body 30, and recovered to its original shape when the external force is removed.
