To provide a deflection measurement unit which shortens fastening force inspection work of each rail fastening device and refastening work of a fastening bolt by a tracklayer.SOLUTION: A deflection measurement unit 100, placed on a leaf spring clip Fc of a rail fastening device F which fixes a rail R on a sleeper S with a fastening bolt Ff1 through the leaf spring clip Fc, measures deflection amount δ near the fastening bolt Ff1 of the leaf spring clip Fc. The deflection measurement unit 100 comprises: a body plate 110 which is placed attachably/detachably with respect to the leaf spring clip Fc of the rail fastening device F; deflection amount measurement means 130 which measures deflection amount δ caused by curvature deformation of the leaf spring clip Fc resulting from the fastening of the fastening bolt Ff1; and result display means 140 which displays the result of measurement by the deflection amount measurement means 130.SELECTED DRAWING: Figure 3
【課題】保線作業員によるレール締結装置ごとの締結力検査作業および締結ボルトの再締結作業の短縮化するたわみ計測ユニットを提供すること。【解決手段】レールＲをまくらぎＳに締結ボルトＦｆ１で板バネクリップＦｃを介して固定するレール締結装置Ｆの板バネクリップＦｃに載置して板バネクリップＦｃの締結ボルトＦｆ１付近のたわみ量δを測定するたわみ計測ユニット１００であって、レール締結装置Ｆの板バネクリップＦｃに対して着脱自在に載置される本体プレート１１０と、締結ボルトＦｆ１の締結に伴う板バネクリップＦｃの湾曲変形で生じるたわみ量δを計測するたわみ量計測手段１３０と、このたわみ量計測手段１３０による計測結果を表示する結果表示手段１４０とを備えている。【選択図】図３
