Thus, the damping member 4 itself can be detached from the damping device 2. As a result, the vibration damping member 4 can be easily maintained and upgraded.

In the vibration damping structure of the vibration damping device 2 as described above, first, the building framework 111 is deformed left and right due to the vibration of the earthquake. In that case, the upper structure portion 12 and the lower structure portion 13 are displaced left and right, and accordingly, the upper support portion 14 and the lower support portion 15 are displaced left and right. Then, the pivot shafts 24 and 22 that pivot the swinging body 3 to both the upper support portion 14 and the lower support portion 15 are displaced to the left and right.
When the pivoting shafts 24 and 22 are displaced to the left and right, the swinging body 3 swings like a pendulum around the central portion between the two pivoting positions (positions of the pivoting shafts 24 and 22). The end of the oscillating body 3 is displaced by amplifying the vibration, whereby the displacement between the upper structure portion 12 and the lower structure portion 13 is amplified.
Therefore, since the deformation of the viscoelastic bodies (vibration control members) 4 and 4 connecting the rocking body 3 and the upper support portion 14 can be amplified, the vibration suppression function can be effectively operated from the small deformation of the skeleton 11. it can.

That is, the amplifying means 7 includes a rotating shaft 34 and is configured to be rotatable, and at least a part of the amplifying means 7 is configured to be extendable and contracted, and is fixed at a predetermined position. A rotation support shaft 35 that rotatably connects the arm member 33 is provided.
The predetermined position at which the rotation support shaft 35 is fixed refers to, for example, a support base (not shown) for fixing the rotation support shaft 35 on the wall surface material 1a. A support base (not shown) is installed between the pillars 11a and 11d so as not to interfere with the operation of the vibration damping device 2. Even when the building is vibrated, it is desirable to have a place where it is difficult to move left and right, or a place where the amount of variation is small even if left and right.

Further, the arm member 33 includes a first arm portion 33 a located on the rocking body 3 side via the rotating shaft 34 and a second arm portion 33 b located on the pointer member 5 side.

It is like that. Although not shown, when the rotary shaft 34 is positioned at the uppermost portion of the long hole 33c, the pointer member 5 is directed downward, and the rotary shaft 34 is at the lowermost portion of the long hole 33c. The position is set so that the rocking body 3 tilts to the maximum and the pointer member 5 swings to the maximum.

  In the present embodiment, the structure using the elongated hole 33c as described above is adopted as the arm member 33 so as to be extendable and contractible. However, the present invention is not limited to this. Other flexible members may be used and can be appropriately changed without departing from the spirit of the present invention.

Further, the amplifying action of the amplifying means 7 can be adjusted by adjusting the length of the first arm portion 33a and the arrangement position of the rotation support shaft 35.
That is, by setting the first arm portion 33a to be shorter and the position of the rotation support shaft 35 to be set higher accordingly, the first arm portion 33a together with the oscillating body 3 is quickly displaced to the left and right.

Therefore, quality control such as maintenance and upgrade of the vibration damping device 2 can be appropriately performed as necessary, and safety in the event of an earthquake is further improved.

  Further, by disposing the tip end portion of the pointer member 5 at a position separated from the swing base point of the swing body 3, the swing width of the tip portion of the pointer member 5 can be increased when the swing body 3 swings. Since it becomes large, even if the vibration which arose in the building is small, it becomes possible to confirm the operating condition of the said damping device 2 reliably.
