The damping means 22 is for damping the horizontal movement of the weight 18, and as shown in FIG.
It is composed of a damping means 22A and two second damping means 22B. The first damping means 22A controls the movement of the weight 18 by X
When the weight 18 is disassembled in the axial direction and the Y-axis direction, a damping force is generated only for the component of the movement of the weight 18 in the X-axis direction. It is configured to generate a damping force only for a motion component. First damping means 22A and second damping means 22B
Are constituted by oil dampers 2202, respectively. Oil damper 2 constituting first damping means 22A
202 is a first linear guide 20 of the first connecting mechanism 20A.
The oil damper 2202 is disposed between the back surface of the guide rail 2008A and the block 2018 facing the back surface, and constitutes the second damping means 22B.
Are disposed between a back surface of the guide rail 2008A of the first linear guide 2008 of the second connection mechanism 20B and a block 2018 facing the back surface. For example, the oil damper 2202 is

Since the vibration damping device 12 according to the present embodiment is configured as described above, for example, as shown by an arrow A in FIG. Considering this, the connecting pieces 2006 attached to the sides of the weight 18 along the Y-axis direction are shown in FIGS. 4, 5B, 6B, and 7.
(B), and the guide 2008B moves upward on the guide rail 2008A with the swing of the connecting piece 2006. However, since the weight 18 does not move in the Y-axis direction, no damping force or restoring force is exerted by the oil damper 2202 or the coil spring 2402 disposed along the Y-axis direction.
No damping force or restoring force is exerted by the damping means 22B and the second restoring force generating means 24B. On the other hand, the connecting piece 2006 attached to the side of the weight 18 along the X-axis direction is shown in FIG.
6B, the connecting piece 2006 simply moves in the −X-axis direction together with the weight 18 as shown in FIG. 6B, and the movement of the connecting piece 2006 causes the oil damper 2202 to have a damping force. Occurs, and the restoring force of the coil spring 2402 is exerted. That is, the first damping unit 22A and the first restoring force generating unit 24A exert a damping force and a restoring force. The allowable limit of the movement of the weight 18 along the X-axis direction is regulated by the collision of the weight 18 with the shock absorber 24 as shown in FIG. 7B.

Similarly, considering the case where a force acts on the weight 18 in the Y-axis direction, the connecting piece 2006 attached to the side of the weight 18 along the X-axis direction is as shown in FIG. The guide piece 2008B
Moves upward on the guide rail 2008A. However, since the weight 18 does not move in the X-axis direction, the oil damper 2202 and the coil spring 2402 disposed along the X-axis direction do not exert any damping force or urging force, and the first damping means 22A Also, no damping force or urging force is exerted by the first restoring force generating means 24A. on the other hand,
Connecting piece 20 attached to the side of the weight 18 along the Y-axis direction
Reference numeral 06 does not swing as shown in FIG.
006 only moves in the Y-axis direction together with the weight 18, and the movement of the connecting piece 2006 causes the oil damper 2202 to move.
Is generated, and the urging force of the coil spring 2402 is exerted. That is, the second damping means 22B and the second restoring force generating means 24B exert a damping force or an urging force. The allowable limit of the movement of the weight 18 along the Y-axis direction is regulated by the collision of the weight 18 with the shock absorber 24 as shown in FIG.

In the above description, the principle of movement has been described in the case where forces in the X-axis direction and the Y-axis direction are separately applied to the weight 18 for the sake of simplicity. The weight 18 is displaced in the intersecting direction even when a force in the intersecting direction acts on the two directions of
The above principle is applied by decomposing into forces in the X-axis direction and the Y-axis direction. Therefore, the vibration damping device 1 according to the embodiment
According to 2, the weight 18 is displaced in any direction in the horizontal plane regardless of the force acting on the horizontal plane.
The damping force and the restoring force of the restoring force generating means 24 act separately in the X-axis direction and the Y-axis direction to reduce the vibration energy of the weight 18 and return the weight 18 to its original position. Therefore, the vibration control device according to the embodiment has the following advantages. The friction resistance of the weight 18 is small. Since the supporting means is constituted by the multi-layer laminated rubber 16, the displacement of the weight 18 can be made large, and it can cope with a long cycle. Further, a plurality of multi-stage laminated rubbers 1 are provided by a stabilizer 1602 extending in the horizontal direction.
6 are connected to each other, and a shock absorber 26 for regulating the maximum amount of movement of the weight 18 is provided, so that the stability is also excellent.
Oil damper 2202 forming damping means 22 and coil spring 2402 forming restoring force generating means 24
Is configured to act only in one of the X-axis direction and the Y-axis direction. Therefore, it is not necessary to consider the non-linearity of the oil damper 2202 and the coil spring 2402, and can be treated linearly. Adjustments can be made easily and precisely.
