PROBLEM TO BE SOLVED: To stably operate a leveling valve.SOLUTION: A leveling valve 100 includes: a piston 20 stored inside a storage hole 11a formed in a housing 10 and moving inside the storage hole 11a depending on a relative displacement amount of a vehicle body 1 relative to a carriage 2; and a rotation regulating part 50 provided in the housing 10 and the piston 20 and regulating the piston 20 from rotating about a first central axis O1 while guiding the piston 20 along a direction of the first central axis O1 of the storage hole 11a.SELECTED DRAWING: Figure 3

    【課題】レベリングバルブを安定して作動させる。【解決手段】レベリングバルブ100は、ハウジング10に形成された収容孔11a内に収容され、台車2に対する車体1の相対変位量に応じて収容孔11a内を移動するピストン20と、ハウジング10及びピストン20に設けられ、収容孔11aの第1中心軸O1方向に沿ってピストン20を案内しつつ、ピストン20が第1中心軸O1を中心に回転することを規制する回転規制部50と、を備える。【選択図】図3
