Abstract
A valve device includes a valve casing, an intermediate rod portion, and an intermediate actuator unit. In the valve casing, a rod insertion hole into which the intermediate rod portioncan be inserted is formed. The intermediate actuator unitincludes a hydraulic cylinder that causes a piston rod portion to advance and retreat in a direction orthogonal to a second center axis direction D. The hydraulic cylinder includes a rod guide portion that guides movement of the piston rod portion. A gap between an inner circumferential surface of the rod insertion hole and an outer circumferential surface of the intermediate rod portionis formed to be wider than a gap between an inner circumferential surface of the rod guide portion and an outer circumferential surface of the piston rod portion.
