The bending portion 15 is supported in parallel to the frame surface by being fixed to the side surface of the column 4A with a fixing tool such as a nail or a screw (not shown).
The movable bracket 12 is a vertically long rectangular plate whose front view is the same as that of the fixed bracket 11. However, the width of the left and right is larger than that of the fixed bracket 11, and the left end surface 16 on the pillar 4A side is shown in FIG. Thus, it is in contact with the right side surface of the column 4A over the entire length in the vertical direction. At the upper and lower corners of the left end including the left end surface 16, chamfers 17 and 17 cut in an inclined plane are formed. Furthermore, the right end of the movable fitting 12 projects to the right relative to the fixed fitting 11 to form a connecting part 18 in which the ends of the braces 14 and 14 are connected outside the fixed fitting 11 by unillustrated bolts and nuts. There is.

The visco-elastic bodies 13 and 13 have a rectangular shape in front view, which is slightly smaller than the fixed fitting 11, and are interposed between the fixed fitting 11 and the movable fitting 12 so that the opposing surfaces to the respective fittings 11 and 12 are bonded. ing.

In the vibration control device 10A shown in FIG. 4, the left end surface 16 of the movable bracket 12 is not in direct contact with the right side surface of the column 4A, but on the strip-like sliding plate 20 fixed vertically to the right side surface of the column 4A. It abuts. The sliding plate 20 is made of resin or metal, and is fixed to the column 4A by bonding or fixing means such as nails and screws.
Therefore, also in the vibration control device 10A, when the movable metal fitting 12 is in sliding contact with the sliding plate 20 on the side of the column 4A at the time the vibration is applied to the frame 1, rotation is suppressed. . Therefore, suitable damping performance is obtained.

As described above, according to the vibration control device 10A of the second embodiment, the movable bracket 12 is supported in a state in which the left end surface 16 on one pillar 4A side is indirectly in contact with the pillar 4A via the sliding plate 20. Thus, the rotational displacement of the movable metal fitting 12 can be suppressed without increasing the size of both the metal fittings 11 and 12 and without causing cross-sectional defects in the viscoelastic body 13. As a result, a compact and low-cost structure can be obtained to obtain stable damping performance.
In particular, here, the sliding plate 20 is provided on the right side of the column 4A with which the left end surface 16 of the movable fitting 12 contacts, so that the movable fitting 12 can be smoothly moved up and down along the sliding plate 20.

The vibration control device 10B shown in FIG. 5 is the same as the embodiment 1 in that the left end surface 16 of the movable fitting 12 is in direct contact with the right side surface of the column 4A. Restraining pieces 21 and 21 which are bent in the direction opposite to the bending part 15 and whose ends are respectively brought close to or abut on the front and rear surfaces of the left end of the movable metal fitting 12 are fixed at the root part on the curved part 15 forming side The metal fitting 11 is formed by cutting and raising at two places at the top and bottom.
Therefore, also in the vibration control device 10B, the movable metal fitting 12 brings the left end surface 16 on the side of the column 4A into contact with the column 4A, so the left end surface 16 follows the right side surface of the column 4A as in the first embodiment. The rotation is suppressed by being guided up and down. At this time, since the end of the movable fitting 12 including the left end face 16 is restrained from being deformed in the front-rear direction (out-of-plane direction of the frame 1) by the restraining pieces 21 and 21 of the fixed fitting 11 and 11, the movable fitting 12 is The fixtures 11, 11 move up and down in parallel with the frame surface without tilting or twisting.

As described above, according to the vibration control device 10B of the third embodiment, the movable bracket 12 is supported in a state in which the left end surface 16 on the side of one of the columns 4A is in direct contact with the columns 4A. , 12, and the rotational displacement of the movable metal fitting 12 can be suppressed without the cross-sectional defects occurring in the viscoelastic body 13. As a result, a compact and low-cost structure can be obtained to obtain stable damping performance.

Further, the length in the vertical direction of the constraining piece can also be changed as appropriate, and changes such as shortening the central portion and lengthening the upper and lower end sides can be made without making all the lengths the same. Constraint pieces may be provided so that they do not align at the front and rear but alternate with each other.
Furthermore, in the third embodiment, the restraint piece is provided on the fixing bracket, but conversely, the left end of the movable fitting is bent toward the fixing bracket and the end approaches the inner surface of the fixing bracket or The restraining piece which abuts may be cut and raised to prevent deformation of the movable metal fitting itself in the direction out of the frame surface.

[Form 4]
In the vibration control apparatus 10C shown in FIG. 6, the left end including the left end surface 16 of the movable fitting 12 is formed long to the left to make the lateral width larger than that of the embodiment 1, and the movable fitting 12 is formed on the right side of the column 4A. The guide groove 5 in which the left end surface 16 abuts on the bottom surface is inserted in the end portion of the guide groove 5 and is recessed in the vertical direction over the entire movable range of the movable metal fitting 12.
Therefore, also in the vibration control device 10C, the movable metal fitting 12 brings the left end surface 16 into contact with the bottom surface of the guide groove 5 of the column 4A. The rotation is suppressed by being guided by the At this time, the left end portion of the movable bracket 12 including the left end surface 16 is inclined or twisted because the movement in the out-of-plane direction of the frame is restrained by the front and rear inner surfaces 6, 6 of the guide groove 5 It moves up and down in parallel with the frame surface between the fixtures 11 and 11 without doing so.

As described above, according to the vibration control device 10C of the fourth embodiment, the movable bracket 12 is supported in a state where the left end surface 16 on one pillar 4A side is in direct contact with the bottom surface of the guide groove 5 of the pillar 4A. Therefore, the rotational displacement of the movable metal fitting 12 can be suppressed without increasing the size of both the metal fittings 11 and 12 and without causing cross-sectional defects in the viscoelastic body 13. As a result, a compact and low-cost structure can be obtained to obtain stable damping performance.
In particular, here, the guide groove 5 into which the left end of the movable fitting 12 including the left end face 16 is inserted is formed in the column 4A over the entire movable range of the movable fitting 12. Since it arrange | positions along the bottom face, the movement to the flame | frame outer surface direction of the movable metal fitting 12 is controlled by the guide groove 5, and it can be made to move up and down in parallel with a flame | frame surface reliably. Therefore, the rotational displacement of the movable fitting 12 can be suppressed more effectively.

  Also in the fourth embodiment, the sliding plate 20 described in the second embodiment is adopted to fix the sliding plate 20 to the bottom surface of the guide groove 5 or to fix the left end of the movable bracket 12. It is acceptable to obtain a vertical guide. Further, the sliding plate 20 can be provided on both the bottom surface of the guide groove 5 and the movable fitting 12 so that the sliding plates 20 are in sliding contact with each other. In these cases, the width of the guide groove 5 is formed wide according to the sliding plate 20.

[Form 5]
The vibration control device 10D shown in FIG. 7 is the same as the embodiment 1 in that the left end surface 16 of the movable fitting 12 directly abuts on the right side surface of the column 4A. At the end portions of the upper and lower braces 14 fixed to each of the upper and lower braces 14, there is provided a rotation restricting surface 22 which is a flat surface in the vertical direction as a rotation restricting portion that abuts on the right end surface of the fixing bracket 11.
Therefore, also in the vibration control device 10D, since the movable metal fitting 12 brings the left end surface 16 on the side of the column 4A into contact with the column 4A, the left end surface 16 follows the right side surface of the column 4A as in the first embodiment. The rotation is suppressed by being guided up and down. At the same time, the rotation restricting surface 22 provided on each brace 14 slides along the right end face of the fixing fitting 11 and is guided up and down, so that the rotation suppressing action can be obtained here as well. Therefore, the movable fitting 12 moves up and down in parallel with the frame surface between the fixed fittings 11 and 11 without tilting or twisting.

As described above, according to the vibration control device 10D of the fifth embodiment, the movable metal fitting 12 is integrated with the rotation restricting portion (the rotation restricting surface 22 of the brace 14) in contact with the right end face of the fixed metal fitting 11 opposite to the column 4A. By providing them, the rotational displacement of the movable metal fitting 12 can be suppressed without increasing the size of both the metal fittings 11 and 12 and without causing cross-sectional defects in the viscoelastic body 13. As a result, a compact and low-cost structure can be obtained to obtain stable damping performance.
In particular, since the rotation restricting portion in contact with the fixed metal fitting 11 is provided in the movable metal fitting 12, the rotation restriction can be easily performed only on the movable metal fitting 12 side.
Further, since each rotation restricting surface 22 is provided at the fixed end of the pair of braces 14 and 14 with the movable fitting 12, the rotation restricting portion can be easily obtained with a rational structure using the brace 14. .

In the fifth embodiment, the left end face 16 of the movable fitting 12 is in contact with the right side face of the column 4A. However, the present invention is not limited to this. As shown in FIG. The vertical movement of the movable fitting 12 may be guided by bringing only the rotation restricting surface 22 of each brace 4 into contact with the right end face of the fixed fitting 11 without contacting the right side face of the movable bracket 12.
In addition, the fixing surface of the brace with respect to the connecting portion of the movable fitting may be on the opposite side to the above-mentioned form 5.

[Form 6]
The vibration control device 10E shown in FIG. 9 is the same as the embodiment 1 in that the left end surface 16 of the movable fitting 12 is in direct contact with the right side surface of the column 4A. Between the upper and lower braces 14, a rotation restricting member 23 as a rotation restricting portion that covers the movable fitting 12 and the fixed fittings 11, 11 from the right side (center side of the frame 1) is attached to the column 4A.
The rotation restricting member 23 is a gate-shaped member formed in a U-shape in a plan view, and the mounting pieces 24, 24 are bent outward at the both ends on the side of the column 4A. The mounting pieces 24, 24 are fixed to the column 4A together with the bending portion 15 by a fixing tool. In this fixed state, the inner surface 25 which is a plane in the vertical direction of the right side base end is brought into contact with the right end face 26 of the movable fitting 12.

  Therefore, also in the vibration control device 10E, since the movable metal fitting 12 brings the left end surface 16 on the side of the column 4A into contact with the column 4A, the left end surface 16 follows the right side surface of the column 4A as in the first embodiment. The rotation is suppressed by being guided up and down. At the same time, the right end face 26 of the movable fitting 12 slides along the inner surface 25 of the rotation restricting member 23 and is guided up and down, so that the rotation suppressing action can be obtained here as well. Therefore, the movable fitting 12 moves up and down in parallel with the frame surface between the fixed fittings 11 and 11 without tilting or twisting.

As described above, according to the vibration control device 10E of the sixth aspect, the rotation restricting portion (rotation restricting member 23) in contact with the right end surface 26 opposite to the pillar 4A in the movable fitting 12 is integrally provided to the pillar 4A. Thus, the rotational displacement of the movable metal fitting 12 can be suppressed without increasing the size of both the metal fittings 11 and 12 and without causing cross-sectional defects in the viscoelastic body 13. As a result, a compact and low-cost structure can be obtained to obtain stable damping performance.
In particular, here, since the rotation restricting member 23 is a gate-shaped member which is fixed to the column 4A by surrounding the fixed fitting 11 and the movable fitting 12 from the center side of the frame 1, the rotation restricting member 23 is the fixed fitting 11 and the movable fitting It can be easily attached to the column 4A across the 12's.

Although the left end face 16 of the movable fitting 12 is in contact with the right side face of the column 4A also in the sixth embodiment, the present invention is not limited to this, and as shown in FIG. Alternatively, only the right end surface 26 may be brought into contact with the inner surface 25 of the rotation restricting member 23 to guide the vertical movement of the movable fitting 12 without contacting the right side surface of the movable bracket 12.
Also, the number of rotation restricting members is not limited to one, and a plurality of rotation restricting members may be provided at intervals in the vertical direction. The attachment structure to the column can also be attached directly to the column without using a fixing bracket.

[Form 7]
The vibration control device 10F shown in FIG. 11 is the same as the embodiment 1 in that the left end surface 16 of the movable fitting 12 directly abuts on the right side surface of the column 4A. The L-shaped rotation restricting plates 27 and 27 as rotation restricting portions are formed by bending the contact pieces 28 orthogonal to the frame surface on the side of the fixing bracket 11 on the front and back surfaces of the fixed bracket 11. And are fixed together with the ends of the braces 14, 14 by means of bolts 29 and nuts 30 in an orientation facing each other. In this fixed state, the front and rear abutment pieces 28, 28 abut on the right end face of the fixing fitting 11, respectively. The end portions of the braces 14 and 14 may be fixed by the bolt 29 and the nut 30 on the outside of any one of the front and rear rotation restricting plates 27 and 27, and the rotation of the connecting portion 18 and either front or rear is restricted. It may be fixed between the plate 27.

  Therefore, in the vibration control device 10F as well, since the movable fitting 12 brings the left end surface 16 on the side of the column 4A into contact with the right side surface of the column 4A, the left end surface 16 corresponds to the right side of the column 4A. The rotation is suppressed by being guided up and down along the. At the same time, the contact pieces 28 and 28 of the rotation restricting plates 27 and 27 provided on the movable bracket 12 slide along the right end face of the fixed bracket 11 and are guided up and down. Be Therefore, the movable fitting 12 moves up and down in parallel with the frame surface between the fixed fittings 11 and 11 without tilting or twisting.

As described above, according to the vibration control device 10F of the seventh embodiment, the movable metal fitting 12 is integrally provided with the rotation restricting portion (rotation restricting plate 27) in contact with the right end face on the opposite side to the column 4A in the fixed metal fitting 11. Thus, the rotational displacement of the movable metal fitting 12 can be suppressed without increasing the size of both the metal fittings 11 and 12 and without causing cross-sectional defects in the viscoelastic body 13. As a result, a compact and low-cost structure can be obtained to obtain stable damping performance.
