To provide a bearing device and an electric vertical takeoff/landing aircraft which have good workability at the time of maintenance, and in which abnormality is hard to occur in a sensor table for sensor output even if creep occurs in a stationary side raceway ring.SOLUTION: A bearing device 6 is equipped with a rolling bearing 7, and a sensor holder 8 that includes a sensor monitoring a state of the rolling bearing 7. An inner ring 9 that is a stationary side raceway ring in the rolling bearing 7 is fitted with and fixed to an axle 18, and the axle 18 is provided with a flange 16 at one end in an axial direction. The sensor holder 8 has an annular portion 13 that is fixed to an outer peripheral surface of the inner ring 9 facing the flange 16 and is provided coaxially with the inner ring 9, a sensor holding portion 14 that is provided on an axial outside surface of the annular portion 13, and a projecting portion 15 that is provided at a circumferential position different from the sensor holding portion 14 on the axial outside surface of the annular portion 13. The sensor holding portion 14 and the projecting portion 15 can be inserted into holes 16a and 16c provided on the flange 16.SELECTED DRAWING: Figure 1

    【課題】メンテナンス時に作業性がよく、静止側軌道輪にクリープが発生しても、センサ出力用のセンサケーブルに異常が発生し難い軸受装置および電動垂直離着陸機を提供する。【解決手段】軸受装置6は、転がり軸受7と、転がり軸受7の状態を監視するセンサを含むセンサホルダ8とを備える。転がり軸受7における静止側軌道輪である内輪9が車軸18に嵌合固定され、車軸18の軸方向一端にフランジ16が設けられる。センサホルダ8は、フランジ16に臨む内輪9の外周面に固定され内輪9と同心状に設けられる円環部13と、円環部13の軸方向外側面に設けられるセンサ保持部14と、円環部13の軸方向外側面でセンサ保持部14とは異なる円周方向位置に設けられる突起部15とを有する。センサ保持部14および突起部15は、それぞれフランジ16に設けられた孔16a,16cに挿入可能とされた。【選択図】図1
