To provide a steering device with an improved degree of freedom in oil passage design.SOLUTION: A steering device includes: a cylinder (12) partitioned into a first chamber (12a) and a second chamber (12b) by a piston (12c); a main valve (11) provided with a first shuttle chamber (11d) and a second shuttle chamber (11e); a normal/reversal-rotation-type hydraulic source (13) including a first discharge opening (13a) and a second discharge opening (13b); a first oil passage (C1) for connecting the first chamber of the cylinder and the first shuttle chamber; and a second oil passage (C2) for connecting the second chamber of the cylinder and the second shuttle chamber. In the main valve (11), either one of the first shuttle chamber (11d) or the second shuttle chamber (11e) is in an open state when the hydraulic source (13) is stopped.SELECTED DRAWING: Figure 2

    【課題】油路設計の自由度を向上させたステアリング装置を提供する。【解決手段】ピストン(12c)によって第1室(12a)及び第2室(12b)に仕切られたシリンダ(12)と、第1のシャトル室(11d)及び第2のシャトル室(11e)を備えたメインバルブ(11)と、第1の吐出口(13a)及び第2の吐出口(13b)を備えた正転逆転方式の油圧源(13)と、前記シリンダの第1室と前記第1のシャトル室とを接続する第1の油路(C1)と、前記シリンダの第2室と前記第2のシャトル室とを接続する第2の油路(C2)と、を備え、前記メインバルブ(11)は、前記油圧源(13)の停止時において、前記第1のシャトル室(11d)及び前記第2のシャトル室(11e)のいずれか一方が開放状態である。【選択図】図2
