To detect the breakage of a bolt by a simple structure.SOLUTION: A bolt 10 is equipped with a shaft portion 11 formed with a male screw portion MS1 on an outer peripheral surface, and is screwed with a counterpart side member so as to attach a wheel 4 of a tire 3 to a hub 8. The shaft portion 11 is formed with a detection hole 13 extending in a first direction in which the shaft 11 extends, having an opening portion on one side in the first direction, and not penetrating on the other side in the first direction. The opening portion 13A can be connected while keeping an airtight state with a connector 30 forming a cylindrical shape.SELECTED DRAWING: Figure 1
【課題】簡便な構成によりボルトの破損を検知する。【解決手段】ボルト10は、外周面に雄ねじ部MS1が形成される軸部11を備え、タイヤ3のホイール4をハブ8に取り付けるために相手側部材に螺合されるボルト10であって、軸部11には、軸部11の延びる第1方向に沿って延びる検知穴13であって、第1方向の一方側に開口部13Aを有し、第1方向の他方側において非貫通とされた検知穴13が形成され、開口部13Aは、筒状をなす接続具30と気密状態を保って接続可能とされている。【選択図】図1
