To provide a wheel looseness detection device which detects looseness of a fastening component of a wheel and further detects monitoring and detection of an engagement state of the wheel.SOLUTION: A wheel looseness detection device is installed in the wheel, and a fastening hole is provided in the wheel. A fastening component is provided to penetrate to the fastening hole, and is fixed thereto. The wheel looseness detection device 1 includes a washer 10, an outer shell, a looseness sensor module, and a power source component 40. The washer 10 has a through hole 11 and a fitting part 12, the fastening component is provided to penetrate to the through hole 11 and the washer 10 is fixed thereto, and the volume of the fastening component covers at least a partial range of the fitting part 12. The outer shell is fit to the fitting part 12, and is used to store the looseness sensor module. The looseness sensor module includes a pressure sensor 31. When the fastening component 3 is tightly fastened thereto and the surface of the wheel 2 is pressed, tight contact force is detected by the pressure sensor 31.SELECTED DRAWING: Figure 2

    【課題】ホイールの締結部品の緩みを検出し、さらにホイールの螺合状態の監視、検出を行うホイール緩み検出装置を提供する。【解決手段】ホイールに設置されており、ホイールには締結穴が備えられている。締結部品は締結穴に貫設されて固定されている。ホイール緩み検出装置1には、ワッシャー10と、外殻と、緩みセンサーモジュールと、電源部品40とが備えられている。ワッシャー10は、貫通穴11と嵌合部12とを有し、貫通穴11に締結部品を貫設させてワッシャー10を固定し、且つ締結部品の体積は少なくとも嵌合部12の一部範囲を覆うものである。外殻は、嵌合部12と嵌合し、緩みセンサーモジュールを収納するのに用いられる。緩みセンサーモジュールは、圧力感知部31を備えている。締結部品3が緊密に締結されてホイール2の表面が押圧されると、圧力感知部31によって緊密力が検出される。【選択図】図2
