A cylinder and a second cylinder, a piston housed inside each of the first and second cylinders so as to be freely displaceable in the axial direction; a piston rod whose displacement in the axial direction is interlocked; the second cylinder is provided with a position detection mechanism having a function of detecting an intermediate position of the piston or the piston rod; Alternatively, the cylinder device is characterized in that the displacement position of the piston of the first cylinder is controlled by a detection signal from the position detection mechanism corresponding to the displacement position of the piston rod. 2. The cylinder device according to claim 1, wherein a proportional control valve is connected to the fluid pressure supply/discharge path to the first cylinder, and the proportional control valve is controlled by a detection signal from the position detection mechanism.
