摘要： 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).

摘要： Provided is a screw motion mechanism capable of facilitating connection of an axial end of a threaded shaft with respect to a structural body while preventing a rotation of the threaded shaft, and capable of preventing application of an excessive torque to a nut member and the threaded shaft and preventing damage on those members. The screw motion mechanism includes: a threaded shaft (30) having an outer peripheral surface provided with a helical thread groove, the threaded shaft (30) having at least one axial end coupled to a first structural body; a nut member (40) held in a rotatable manner with respect to a second structural body which is movable in an axial direction of the threaded shaft with respect to the first structural body, the nut member (40) being threadedly engaged with the threaded shaft; and a spherical joint (32) for coupling the at least one axial end of the threaded shaft (30) to the first structural body, the spherical joint (32) including: a spherical portion (33, 61); and a sphere receiving portion (36, 60) for housing the spherical portion. When assuming an axial force applied to the threaded shaft (30) as a variable, a line of a rotational torque intersects with a line of a sliding torque in a graph, and the sliding torque exceeds the rotational torque under an initial state in which the axial force is not applied to the threaded shaft (30).

摘要： An eddy current damper (1) includes a screw shaft (7), a plurality of first permanent magnets (3), a plurality of second permanent magnets (4), a cylindrical magnet holding member (2), a cylindrical conductive member (5) having a conductivity, and a ball nut (6) meshing with a screw shaft (7). The screw shaft (7) is movable in the axial direction. The first permanent magnets (3) are arrayed along the circumferential direction around the screw shaft (7). The second permanent magnet (4) is arranged between the first permanent magnets (3) leaving gaps with the first permanent magnets (3), wherein the arrangement of magnet poles is inverted between the second permanent magnet (4) and the first permanent magnet (3). The magnet holding member (2) holds the first permanent magnet (3) and the second permanent magnet (4). The conductive member (5) is opposed to the first permanent magnets (3) and the second permanent magnets (4) with a gap therebetween. The ball nut (6) is disposed inside the magnet holding member (2) and the conductive member (5), and is fixed to the magnet holding member (2) or the conductive member (5).
