Zusammenfassung:	To provide an inspection tool for an obstacle detector which allows various different obstacle detectors to make an inspection easily.SOLUTION: An inspection tool 10 includes: holders 30A to 30D holding attenuation filters 20A to 20D, respectively, with different attenuation rates; an attachment unit 30E attached to a light receiver 110 of the obstacle detector; and a shaft 40. The holders 30A to 30D are provided with guide frames 38A to 38D. The holders 30A to 30D are supported to be axially rotatable around the shaft 40 and axially rotate in a range of 90° from a center position.SELECTED DRAWING: Figure 3 【課題】様々な障検装置に対し、容易に検査を行うことができる障検装置の検査器具を提供する。【解決手段】検査器具１０は、減衰率が互いに異なる減衰フィルタ２０Ａ〜２０Ｄをそれぞれ保持するホルダ３０Ａ〜３０Ｄと、障検装置の受光器１１０に取り付けられる取り付け部３０Ｅと、シャフト４０とを備え、ホルダ３０Ａ〜３０Ｄには、ガイド枠３８Ａ〜３８Ｄが形成されている。ホルダ３０Ａ〜３０Ｄは、シャフト４０周りに軸回転可能に支持され、中心位置から９０°の範囲で軸回転する。【選択図】図３
