Zusammenfassung:Provided is a damping device that is smaller in size and capable of increasing a damping force with respect to vibrational energy that is propagated between two structural bodies. The damping device includes: a fixed cylinder (2) that is configured to be fixed to a first structural body and formed into a cylindrical shape so as to comprise a hollow portion; a shaft member (3) that is configured to be fixed to a second structural body, the shaft member (3) being housed in the hollow portion of the fixed cylinder (2) and having an outer peripheral surface provided with a helical thread groove; a nut member (4) that is threadedly engaged with the shaft member, and converts an axial motion of the shaft member into a rotational motion; a rotor member (6) that is formed into a cylindrical shape so as to cover the fixed cylinder (2) and to form a cylindrical accommodation chamber (8) between the rotor member (6) and an outer peripheral surface of the fixed cylinder, and is rotated by the nut member (4); and viscous fluid (7) that is sealed in the cylindrical accommodation chamber (8).
