To provide a fuel tank grounding detection device that is able to detect an anomaly relative to a fuel tank at an early stage while grasping a pressure in a fuel tank without using an external pressure sensor.SOLUTION: A slide type sensor 30 is provided in a fuel tank body 10, which has a telescopic support post 20 extended telescopically between an upper wall and a lower wall and detects an amount of displacement of a length of the telescopic support post 20. Based on an amount of displacement input from the slide type sensor 30, the fuel tank grounding detection device estimates a pressure in the fuel tank body 10 and detects an impact to the lower part of the fuel tank body 10.SELECTED DRAWING: Figure 1

    【課題】外付けの圧力センサーを用いずに、燃料タンク内の圧力を把握しつつ、燃料タンクに対する異常を早期に検知することができる燃料タンク接地検知装置を提供する。【解決手段】燃料タンク本体10内に、上壁と下壁との間に伸縮可能に架設された伸縮支柱20を有し、伸縮支柱20の長さの変位量を検出するスライド式センサー30を備える。燃料タンク接地検知装置は、スライド式センサー30から入力された変位量に基づいて、燃料タンク本体10内の圧力を推定するとともに、燃料タンク本体10の下部への衝撃の検知を行う。【選択図】図1
