PROBLEM TO BE SOLVED: To provide a fluid transportation device, in which damaging of a tube is prevented and a cam drive force is reduced.
SOLUTION: The fluid transportation device 10 includes: the tube 50 having elasticity a tube restriction part 55c restricting the position of the tube 50 a rotatable cam 20 disposed to be separated from the tube 50 fingers 40-46 disposed between the tube 50 and the cam 20 and moving back and forth toward the tube restriction part 55c along with rotation of the cam 20 and an elastic ring 29 provided on at least either the fingers 40-46 or the cam 20 and deformable in a back and forth direction of the fingers 40-46. The cam 20 has first to fourth cam bodies 21-24 respectively pressing and moving the fingers 40-46 toward the tube restriction part 55c. The first to fourth cam bodies 21-24 are movable in the back and forth direction of the fingers 40-46 by the elastic ring 29.
