PROBLEM TO BE SOLVED: To provide a fluid detector which has additional functions in addition to a fluid detecting function and can be smaller than the case where respective functions are separately installed in the detector, and can surely operate whatever their arrangement is. SOLUTION: The fluid detector for detecting fluid flow in a passage comprises a moving body to be moved by the fluid flow, an elastic body abutting against the moving body and giving resilient force in the reverse direction of the flow in the passage, and means for detecting the movement of the moving body, wherein the moving body and the elastic body have additional functions in addition to the fluid detecting function. |
