To provide a control valve capable of holding a valve element at a predetermined position with a simple structure, and a control valve device and a vehicle body tilting device, which have the control valves.SOLUTION: A valve element 40 of a control valve 10 is moved vertically. In the valve element 40, there are formed: a command pressure-receiving surface 50 that is directed downward to face a command chamber 13; a first pressure-receiving surface 51 that is directed downward to face an air introduction chamber 14 and has a smaller area than the area of the command pressure-receiving surface 50; a second pressure-receiving surface 52 that is directed upward opposite to the first pressure-receiving surface 51, faces a back pressure side chamber 15, and has an area that is smaller than the area of the command pressure-receiving surface 50 and larger than the area of the first pressure-receiving surface 51; and an inner flow passage 54 that connects the first pressure-receiving surface 51 with the second pressure-receiving surface 52.SELECTED DRAWING: Figure 2

    【課題】簡易な構造で弁体を所定の位置に保持可能な制御弁、及び、この制御弁を備える制御弁装置と車体傾斜装置とを提供する。【解決手段】制御弁10の弁体40は上下動し、弁体40には、下方を向いて指令室13に面する指令用受圧面50と、下方を向いて空気導入室14に面するとともに指令用受圧面50の面積より小さな面積を有する第一受圧面51と、第一受圧面51とは反対側となる上方を向くとともに背面側室15に面し、指令用受圧面50の面積よりも小さく、かつ第一受圧面51の面積よりも大きな面積を有する第二受圧面52と、第一受圧面51と第二受圧面52とを接続する内部流路54と、が形成されている。【選択図】図2
