To provide a fluid transportation device capable of transporting fluid such as water from a lower part to an upper part.
The fluid transportation device is provided with a fluid transportation pipe 11 having a fluid inlet 21 and a fluid outlet 22 in separate positions in an axial direction, a spiral member 12 spirally extending between at least the fluid inlet and the fluid outlet of the fluid transportation pipe and rotatably fitted in the fluid transportation pipe, a rotation driving device 14 for rotating the spiral member in the fluid transportation pipe, and a rotation speed adjusting mechanism for adjusting a rotation speed of the spiral member so that the fluid flows from the fluid inlet to the fluid outlet along the spiral member by the centrifugal force when the spiral member is rotated.
