To provide a hydraulic cylinder device which is configured to include two pistons and has a structure capable of improving mountability.SOLUTION: A large-diameter piston 104 and a small-diameter piston 106, which constitute a hydraulic cylinder device 100, are arranged in series, and a first hydraulic chamber 112 and a second hydraulic chamber 114 are also provided adjacent to the large-diameter piston 104 and the small-diameter piston 106, so that the hydraulic cylinder device 100 tends to be long in the moving direction of the respective pistons 104, 106. In contrast, in the hydraulic cylinder device 100, the large-diameter piston 104, the small-diameter piston 106, the first hydraulic chamber 112, and the second hydraulic chamber 114 are arranged in a common counter shaft 50, respectively, and therefore, even if the hydraulic cylinder device 100 becomes long in the moving direction of the pistons, it can be mounted. Accordingly, the mountability of the hydraulic cylinder device 100 is improved.SELECTED DRAWING: Figure 2

    【課題】2つのピストンを備えて構成される油圧シリンダ装置において、搭載性を向上できる構造を提供する。【解決手段】油圧シリンダ装置100を構成する大径ピストン104および小径ピストン106は直列に配置され、第1油圧室112および第2油圧室114についても、大径ピストン104および小径ピストン106に隣接して設けられるため、油圧シリンダ装置100は、各ピストン104、106の移動方向において長くなる傾向にある。これに対して、油圧シリンダ装置100にあっては、大径ピストン104、小径ピストン106、第1油圧室112、および第2油圧室114が、共通のカウンタ軸50内にそれぞれ配置されることで、油圧シリンダ装置100がピストンの移動方向に長くなっても搭載が可能になる。よって、油圧シリンダ装置100の搭載性が向上する。【選択図】図2
