To cause an appropriate damping force to work according to a relative displacement with a simple configuration. A movable inner cylinder 3 slidable in an outer cylinder 2 in an axial direction and having orifices 31 formed in its peripheral wall 31 is provided, a piston 5 around which a linear member 52 that generates a frictional force is wound is further provided in the movable inner cylinder 3, and a viscous liquid 7 is filled in the outer cylinder 2 including the inside of the movable inner cylinder 3. Accordingly, when the piston 5 moves together with the movable inner cylinder 3, a high damping force is not exerted, whereas when the piston 5 relatively moves in the movable inner cylinder 3, the high damping force is exerted owing to viscous friction between the piston 5 and the movable inner cylinder 3 and the viscous resistance of the viscous liquid passing through the orifices.
