A weight is disposed in an arbitrary story of a structure so as to be movable relative to a direction of motion of the structure. Rotary members are supported in the weight. Rigid members meshing with gears provided on each rotary member are slidably fitted in the weight. These rigid members are respectively coupled to a ceiling and a floor via coupling members. The rotary members and the rigid members are disposed on the weight in correspondence with two horizontal directions. As a result, a horizontal motion of the floor of the structure is temporarily converted into a rotational motion by the rotary members, and is then converted into a horizontal motion so as to be transmitted to the ceiling. At this time, since the rotary members are pivotally supported in the weight, the weight can be moved in the opposite direction to that of the floor without undergoing an arcuate motion, thereby exhibiting the effect of reducing an input of vibration.

A vibration suppressing apparatus for a structure comprising: a mass supported so as to be movable relative to a direction of motion of said structure; first rigid members disposed in an upper portion of said mass in directions of two horizontal axes, respectively, and fitted slidably in said mass; second rigid members disposed in a lower portion of said mass in directions of two horizontal axes, respectively, and fitted slidably in said mass; rotary members pivotally supported in said mass and each having a large-diameter portion at one end of a rotating shaft and a small-diameter portion at another end of said rotating shaft, said rotary members being adapted to be movable together with said mass; and transmitting means for converting a horizontal motion of said second rigid member into a rotational motion to allow the rotational motion to be transmitted to one of said diameter portions of said rotary member, and for converting a rotational motion of the other one of said diameter portions into a horizontal motion to allow the horizontal motion to be transmitted to said first rigid member.
