<p>PROBLEM TO BE SOLVED: To provide an abnormality detecting device of a fuel tank capable of detecting excessive negative pressure (that is, internal pressure abnormality) of the fuel tank by an inexpensive constitution without the addition of a pressure sensor.SOLUTION: An abnormality detecting device 1 includes: a fuel sender gage 5 provided on a bottom surface 31a side of a fuel tank 3; a connector 7 provided in a halfway of wiring H of the fuel sender gage 5 and separated when a tensile load of equal to or more than a prescribed value is applied; a first hook 9a disposed on a ceiling surface 31b side of the fuel tank 3; and a second hook 9b disposed on the bottom surface 31a side of the fuel tank 3. The first hook 9a is arranged in a position in which an interval between the first hook 9a and the second hook 9b is extended when the ceiling surface 31b is recessed to the bottom surface 31a side, the second hook 9b is arranged in a position in which the interval between the second hook 9b and the first hook 9a is extended when the bottom surface 31a is recessed to the ceiling surface 31b side, and the wiring H is hooked on an upper surface of the second hook 9b, and is hooked on a lower surface of the first hook 9a, and is arranged on the ceiling surface 31b side.</p> |
