Abstract

To provide a cylinder device and a valve device capable of adjusting attenuation force in more detail.SOLUTION: A cylinder device includes: an annular disc 105 whose inner peripheral side or outer peripheral side is supported, having a gap with a case member 100 or with a shaft part 28 on a non-supported side, which can be bent on one axial direction side and on the other axial direction side; first movement regulation members 102 and 103 for regulating the movement on the one axial direction side of the annular disc 105; second movement regulation members 107 and 108 for regulating the movement on the other axial direction side of the annular disc 105; first movement distance adjusting means 104 provided between the annular disc 105 and the first movement regulation member 103 capable of adjusting a movement distance on the one axial direction side of the annular disc 105; and second movement distance adjusting means 106 provided between the annular disc 105 and the second movement regulation member 107 capable of adjusting a movement distance on the other axial direction side of the annular disc 105.SELECTED DRAWING: Figure 3
