摘要： A cam member 5 is disposed within a first chamber R1 such that the cam member 5 is rotatable but non-movable in the axial direction. The cam member 5 is non-rotatably connected to a rotor 3 through a connection shaft portion 52 piercing into a piston 4. A second cam mechanism 10 is disposed between the cam member 5 and the piston 4. When the cam mechanism 7 causes the piston 4 to move from the second chamber R2 side to the first chamber R1 side in accordance with rotation of the rotor 3 in one direction, the second cam mechanism 10 allows the piston 4 to move from the second chamber R2 side to the first chamber R1 side by the same amount of movement. When the second cam mechanism 10 causes the piston 4 to move from the first chamber R1 side to the second chamber R2 side in accordance with rotation of the rotor 3 in the other direction, the cam mechanism 7 allows the piston 4 to move from the first chamber R1 side to the second chamber R2 side by the same amount of movement.

摘要： A damping device for damping the relative rotation of a rotating member. The damping device includes a casing, a rotor disposed in an interior space of the casing, and a damping mechanism including a viscous liquid disposed in an annular chamber formed between the casing and the rotor. The viscous liquid exerts frictional forces to damp the relative rotation between the rotor and the casing in a first rotation direction but not in the opposite rotation direction, the damping force increasing when the rotor and the casing rotate relative to each other from a first relative angular position to a second relative angular position in the first rotation direction. The casing and the rotor are structure to provide a damping force by impeding the flow of the viscous liquid within the chamber, and to provide another damping force by the contacting of the rotor and the casing. A valve is further provided within the chamber to restrict the flow of the viscous liquid. A toilet seat and lid unit incorporating two identically shaped damping devices, as well as a toilet bowl incorporating the seat and lid unit are also provided.
