Description

  The present invention relates to a vibration absorber that is installed in parallel to the pillars of a building or the like in a wall of a building or the like in parallel with the pillars in a vertical direction to attenuate vibration caused by an earthquake of the building or the like, and the vibration absorber is attached to the wall of the building. The present invention relates to a seismic control structure that is installed in a brace or on a column that is substantially parallel to the column and extends in a substantially vertical direction.

  Here, d is a thickness in a direction orthogonal to the axial direction of the gap, and t is a thickness in a direction orthogonal to the axial direction of at least one of the outer and inner long bodies.

  In the vibration absorber according to the present invention, a damping force is generated by causing shear deformation in the viscous body or the viscoelastic body disposed in the gap by the relative axial movement of the inner long body with respect to the outer long body.

  In the vibration absorber 7, the mounting plate members 31 and 32 are fitted into the slits 43 and 46 formed in the long body 21 and the long body 22, respectively, and are fixed to the long body 21 and the long body 22. Therefore, the fixing of the mounting plate members 31 and 32 to the long body 21 and the long body 22 can be made stronger, and each of the mounting plate members 31 and 32 can be used for a long time. And the inconvenient situation which will remove | deviate from the elongate body 22 can be avoided.

  In addition, in the vibration absorber 7, the product (d 1 · t 1) of the thickness d 1 of the gap 25 and the thickness t 1 of the cylindrical portion 36 is 10 or more and 100 or less, and the thickness d 1 of the gap 25 and the thickness of the cylindrical portion 36. The ratio (t1 / d1) to t1 is 0.5 or more and 8 or less, and the product (d1 · t2) of the thickness d1 of the gap 25 and the thickness t2 of the cylindrical portion 38 is 10 or more and 100 Since the ratio (t2 / d1) between the thickness d1 of the gap 25 and the thickness t2 of the cylindrical portion 38 is 0.5 or more and 8 or less, the cylindrical portion 36 regardless of the thickness d1. And 38 are sufficiently strong, and the vibration absorber 7 having cylindrical portions 36 and 38 having a weight and a diameter corresponding to the magnitude of the generated damping force can be provided. The heat generated in the body 26 is efficiently and quickly passed through the cylindrical portions 36 and 38. In this way, the temperature rise of the viscous body 26 itself can be eliminated and an intended damping force can be generated. In addition, the relative movement of the elongated body 22 relative to the elongated body 21 in the axial direction X is also large. Since no pressure fluctuation is caused, vibrations caused by earthquakes such as buildings can be efficiently damped.

  By the way, the above-described vibration absorber 7 includes an outer long body 21 and an inner long body 22, but instead, as shown in FIGS. The vibration absorber 101 may be configured by including a hollow long body 102 in addition to the long body 22.

  In the vibration absorber 101 shown in FIGS. 7 to 10, the long body 22 is an intermediate long body positioned between the long body 21 and the long body 102, and the long body 102 is the long body 21. And it becomes an inner elongate body arranged inside with respect to both the elongate body 22.

  In the vibration absorber 101, the outer long body 21 includes an annular bottom portion 103 that is integral with the cylindrical portion 36 instead of the disc-shaped bottom portion 35, and the long body 21 and an intermediate long body. The inner hollow long body 102 made of a cylindrical member is provided with a disk-like bottom portion 104 and a cylindrical portion 106 that is integral with the bottom portion 104 and is closed at one end 105 side by the bottom portion 104. The long body 21 is integrated with the long body 102 with the bottom 103 fixed to the bottom 104 by welding or the like, and the cylindrical portion 106 of the long body 102 is A cylindrical body of the elongated body 22 has a cylindrical outer surface 109 extending in the axial direction X disposed with a gap 108 with respect to a cylindrical inner surface 107 extending in the axial direction X of the cylindrical portion 38 of the elongated body 22. Inserted in part 38 so as to be relatively movable in the axial direction X Is inserted in the axial direction X from the insertion part 110 and protrudes from the other end part 112 on the opening end 111 side in the axial direction X of the cylindrical part 38 to the outside of the cylindrical part 38. In addition to the gap 25, the viscous body 26 is disposed in the gap 108 in addition to the gap 25 in contact with the inner surface 107 and the outer surface 109. The outer long body is fitted into the slit 43 formed in the bottom portion 103 and the other end portion 29 of the cylindrical portion 36 and the slit 113 formed in the bottom portion 104 of the long body 102 and the one end portion 105 of the cylindrical portion 106. 21 and the other end portion 29 of the cylindrical portion 36 and the bottom portion 104 of the elongated body 102 and the one end portion 105 of the cylindrical portion 106. The viscous body 26 is other than the gaps 25 and 108 and the gaps 25 and 108. of In addition to the interior of the tubular portion 36 and 38, it is densely packed in the inside of the cylindrical portion 106.

  In the vibration absorber 101, spacer pieces 121, 122, and 123 that are equivalent to the spacer piece 57 of the spacer member 55 are the outer surface 24 of the other end portion 112 of the cylindrical portion 38 and the outer surface 109 of the cylindrical portion 106 on the one end portion 105 side. And the outer surfaces 109 of the other end portions 124 of the cylindrical portion 106 are fixed, and the outer surfaces of the spacer pieces 121, 122, and 123 are axially directed to the inner surface 23 of the cylindrical portion 36 and the inner surface 107 of the cylindrical portion 38, respectively. Further, the gaps 25 and 108 are held by being relatively slidably contacted in a direction R around the axis 60.

  Also in the vibration absorber 101, the long bodies 21 and 102 and the long body 22 are relatively movable in the axial direction X, and the mounting plate member 31 fixed to the long bodies 21 and 102 has a wide width. The attachment surface 61 is substantially parallel to the wide attachment surface 62 of the attachment plate member 32 fixed to the elongated body 22. The long bodies 21 and 102 and the long body 22 in this example are relatively rotatable in the direction R around the axis 60.

  Further, in the vibration absorber 101, the thickness of the gap 25 in the direction perpendicular to the axial direction is d1, the thickness of the gap 108 in the direction perpendicular to the axial direction is d2, and the outer and inner elongated bodies 21 and 102, and At least one of the intermediate long bodies 22, in this example, the thicknesses of the cylindrical portions 36, 38 and 106 of the long bodies 21, 22 and 102 in the direction perpendicular to the axial direction are respectively t1, t2 and t3. Then, the thicknesses d1 and d2 and the thicknesses t1, t2, and t3 have a relationship of the following expressions (7) to (14).

(Equation 17)
10 ≦ d1 · t1 ≦ 100 (7)

(Equation 18)
0.5 ≦ t1 / d1 ≦ 8 (8)

(Equation 19)
10 ≦ d1 · t2 ≦ 100 (9)

(Equation 20)
0.5 ≦ t2 / d1 ≦ 8 (10)

(Equation 21)
10 ≦ d2 · t2 ≦ 100 (11)

(Equation 22)
0.5 ≦ t2 / d2 ≦ 8 (12)

(Formula 23)
10 ≦ d2 · t3 ≦ 100 (13)

(Equation 24)
0.5 ≦ t3 / d2 ≦ 8 (14)

  The above-described vibration absorber 101 is similar to the vibration absorber 7 in that the wide attachment surfaces 61 and 62 of both the attachment plate members 31 and 32 are arranged in parallel to the surface of the wall space 6, as shown in FIG. It is connected to the lower horizontal member 5 via 65 and to the upper horizontal member 4 via connecting means 66, and is used in the damping wall structure 1 instead of the vibration absorber 7.

  The damping wall structure 1 including the vibration absorber 101 can obtain the same effect as the above-described vibration damping wall structure 1 including the vibration absorber 7, and the long wall 21 and 102 due to an earthquake or the like is long. By the relative movement of the body 22 in the axial direction X, in addition to the viscous body 26 disposed in the gap 25, the viscous body 26 disposed in the gap 108 can also cause viscous shear deformation to absorb relative vibration energy. As a result, the vibration due to the earthquake or the like of the building can be attenuated at an earlier stage. In addition, in the vibration absorber 101, as with the vibration absorber 7, the mounting plate members 31 and 32 are respectively connected to the long bodies 21, 22 and 102. Adhesion can be further strengthened, and an inconvenient situation in which each of the mounting plate members 31 and 32 is detached from the long bodies 21, 22, and 102 after long-term use can be avoided.

  In the vibration absorber 101, the cylindrical portions 36, 38 and 106 of the long bodies 21, 22 and 102 are sufficiently strong regardless of the thicknesses d1 and d2, and the generated damping force is reduced. In addition to providing the vibration absorber 101 having the cylindrical portions 36, 38 and 106 having a weight and diameter corresponding to the size, the long body 21, the heat generated in the viscous body 26 can be efficiently and quickly obtained. It is possible to escape through the respective cylindrical portions 36, 38 and 106 of 22 and 102 to eliminate the temperature rise of the viscous body 26 itself and to generate the intended damping force. Even when the body 22 is moved in the relative axial direction X, the viscous body 26 does not cause large pressure fluctuations, so that vibrations caused by earthquakes such as buildings can be efficiently damped.

  In the above description, it is the vibration absorber 7 having one long body 21 and one long body 22 or the vibration absorber 101 having one long body 21, 22 and 102, respectively. A plurality of long bodies 21, 22 and 102, a plurality of long bodies 21, 22 and 102, and a plurality of long bodies 21, 22, 102 and 202 described later. For example, as shown in FIGS. 11 to 13, two sets of the long body 21 and the long body 22 may be provided to constitute the vibration absorber 131. In the vibration absorber 131 shown in FIGS. The two long bodies 21 are fixed and integrated with each other by welding or the like, and the mounting plate member 31 is fixed to each long body 21 in the same manner as described above and is attached to each long body 21. The mounting plate member 32 is also fixed to each long body 22 in the same manner as described above, and is attached to each long body 22. To have been shared.

  In the vibration absorber 131, the cylindrical body 51 of the holding means 33 has an elliptical shape instead of a cylindrical shape, and surrounds one end portion 28 of the long bodies 21 and 22 in the same manner as the mounting plate members 31 and 32. The scales 21 and 22 are shared.

  Similarly to the vibration absorber 7, the vibration absorber 131 is also connected via the connecting means 65 so that the wide attachment surfaces 61 and 62 of both the attachment plate members 31 and 32 are arranged parallel to the surface of the wall space 6. The horizontal member 5 is connected to the upper horizontal member 4 via the connecting means 66 and can be used in the vibration control wall structure 1 instead of the vibration absorber 7. Relative movement of the two elongated bodies 22 relative to the two elongated bodies 21 due to an earthquake or the like in the axial direction X causes viscous shear deformation to occur in the viscous bodies 26 arranged in the two gaps 25, thereby causing relative movement. As a result of absorbing vibration energy, vibrations due to earthquakes of buildings can be attenuated more quickly. The same applies to the case of a vibration absorber having a plurality of long bodies 21, 22 and 102 and a plurality of long bodies 21, 22, 102 and 202.

  In any of the above-described vibration absorbers 7, 101, and 131, the opening end 27 of the long body 21 is left open as it is, but in order to prevent rainwater and dust from entering the gap 25 from the opening end 27, for example, FIG. As shown in FIG. 5, when the viscous body 26 is sealed by closing the opening end 27 with the seal member 141 in the vibration absorber 7, the axial direction X of the insertion portion 39 of the long body 22 with respect to the inside of the long body 21. The vibration absorber 7 may be configured by including suppression means 142 that suppresses the increase / decrease in the internal pressure of the viscous body 26 during the forward / backward movement.

  The suppression means 142 shown in FIG. 14 defines the inside of the cylindrical portion 38 which is a hollow portion of the long body 22 into a chamber 144 filled with the viscous body 26 and an air chamber 146 and increases or decreases the internal pressure of the viscous body 26. A bellows-like flexible partition wall 145 made of a rubber member or the like for increasing or decreasing the volume of the chamber 144 is provided, and the outer peripheral end of the flexible partition wall 145 is fixed to the inner surface 107 of the cylindrical portion 38. In the case of such suppressing means 142, the air chamber 146 adjacent to the chamber 144 defined by the flexible partition wall 145 inside the cylindrical portion 38 may be filled with air and sealed. If necessary, a through hole 147 may be drilled in the cylindrical portion 38 so that the air chamber 146 communicates with the outside.

  In each of the vibration absorbers 7 and 101, the outer peripheral end of the flexible partition 145 is fixed to the inner surface 107 of the cylindrical portion 38 and the flexible partition 145 is disposed inside the cylindrical portion 38 instead of being fixed to the inner surface 107 of the cylindrical portion 38. May be fixed to the inner surface 23 of the cylindrical portion 36 and a flexible partition wall 145 may be disposed inside the cylindrical portion 36. In short, the air chamber 146 that can suppress the increase and decrease of the internal pressure of the viscous body 26 in operation is formed. The vibration absorbers 7 and 101 may be arranged.

  Further, as shown in FIG. 15, instead of the flexible partition wall 145 or together with the flexible partition wall 145, the restraining means 142 is an air bag, foam rubber or sponge embedded in the viscous body 26 filled in the cylindrical portion 38. A compressible body 148 such as the above may be provided. Instead of embedding such a compressible body 148 in the viscous body 26 filled in the inside of the cylindrical portion 38 or together with this, the viscous body 26 outside the cylindrical portion 38 and filled in the inside of the cylindrical portion 36 or FIG. In the case of the vibration absorber 101 shown in FIG. 2, the vibration absorber 101 may be embedded in the viscous body 26 filled in the cylindrical portion 106, and the compressible body 148 can also suppress increase / decrease in the internal pressure of the viscous body 26 in operation. As such, it may be embedded in the viscous body 26.

  For example, when the flexible partition wall 145 is disposed inside the cylindrical portion 38 of the elongated body 22 in the vibration absorber 101, the elongated body 102 may be formed of a solid member instead of a hollow member, 16, the long body 102 may be formed of a hollow member having a cylindrical portion 106 closed at the other end portion 124 side and at the bottom portion 149. In the vibration absorber 101 shown in FIG. The portion 106 may not be filled with a viscous material.

  Each of the vibration absorbers 7, 101, and 131 described above has each mounting means constituted by a single mounting plate member 31 and 32, but instead of this, as shown in FIGS. In addition to the plate members 31 and 32, there is still another one attachment plate member 151 and 152, that is, one attachment means provided with one pair of attachment plate members 31 and 151 and the other pair of attachment plate members 32 and For example, the vibration absorber 7 may be configured with the other attachment means provided with 152.

  One other mounting plate member 151 includes mounting plate pieces 155 and 156, and the mounting plate piece 155 has slits 157 formed in the bottom portion 35 and the cylindrical portion 36, similarly to the mounting plate member 31. Are attached to the bottom portion 35 and the cylindrical portion 36 and the mounting plate member 31 by welding or the like, and the mounting plate piece 156 is formed on the bottom portion 35 and the cylindrical portion 36 in the same manner as the mounting plate piece 155. The wide surface 159 of the mounting plate member 151 composed of the mounting plate pieces 155 and 156 is fitted to the slit 158 and fixed to the bottom 35 and the cylindrical portion 36 and the mounting plate member 31 by welding or the like. It intersects with the 31 wide mounting surface 61, and is orthogonal in this example.

  The other other mounting plate member 152 includes mounting plate pieces 165 and 166, and the mounting plate piece 165 has slits 167 formed in the bottom portion 37 and the cylindrical portion 38 in the same manner as the mounting plate member 32. The mounting plate piece 166 is formed on the bottom portion 37 and the cylindrical portion 38 in the same manner as the mounting plate piece 165, and is fixed to the bottom portion 37 and the cylindrical portion 38 and the mounting plate member 32 by welding or the like. The wide surface 169 of the mounting plate member 152 composed of the mounting plate pieces 165 and 166 is fitted to the slit 168 and fixed to the bottom portion 37 and the cylindrical portion 38 and the mounting plate member 32 by welding or the like. It intersects with the 32 wide mounting surfaces 62 and is orthogonal in this example.

  17 to FIG. 21, the wide surface 159 of the mounting plate member 151 is orthogonal to the wide mounting surface 61 of the mounting plate member 31, and the wide surface 169 of the mounting plate member 152 is mounted. Since it is orthogonal to the wide mounting surface 62 of the plate member 32, the bending strength of the mounting plate members 31 and 32 can be increased.

  Although the vibration absorbers 7 and 101 described above are configured to include the holding means 33, the holding means 33 is temporarily fixed to the long body 21 before the vibration absorbers 7 and 101 are installed in the wall space 6 via the connecting means 66. After the installation to the wall space 6 through the connecting means 66, the bolts 50 and 54 are loosened to remove the holding means 33, and the damping wall structure 1 is provided with the vibration absorber 7 or 101 without the holding means 33. In this case, a spacer piece similar to the spacer pieces 121, 122, and 123 may be newly added or added between the cylindrical portion 36 and the cylindrical portion 38 and between the cylindrical portion 38 and the cylindrical portion 106. It may be appropriately arranged as necessary.

  Further, in the vibration absorber 7 or 101 without the holding means 33, a storage means for storing the viscous body 26 that overflows from the gap 25 due to a temperature rise may be provided. For example, as shown in FIG. 22, the storage unit 171 provided in the vibration absorber 101 includes a cylindrical body 174 fixed to the outer surface 173 of the one end portion 28 of the cylindrical portion 36 in the long body 21. The outer surface 24 of the cylindrical body 174 and the inner surface 175 of the cylindrical body 174 form an annular storage space 177, the viscous body 26 leaks from the storage space 177 to the outside of the vibration absorber 101, and the storage space from the outside of the vibration absorber 101. In order to prevent rainwater and dust from entering 177, the outer surface 24 of the cylindrical portion 38 of the elongated body 22 is slidable in the axial direction X, while the inner surface 175 of the cylindrical body 174 is slidable. An annular lid member 176 is fitted between the cylindrical portion 38 and the cylindrical body 174 so as to be fixed. In the storage space 177, the width ds in the direction orthogonal to the axial direction X is larger than the thickness d1, so that even if a large amount of the viscous body 26 overflows from the gap 25, it can be stored in the storage space 177 without any problem. Be able to. Of course, such storage means 171 may be provided in the vibration absorber 7 in the same manner.

  In the vibration absorber 101 shown in FIG. 16 described above, the suppressing means 142 is configured by the flexible partition wall 145. Instead of this, as shown in FIG. 22, a disk-like blockage is formed inside the one end portion 105 of the cylindrical portion 106. The member 181 is fixed to define the inside of the cylindrical portion 106 into a closed space 182 and a space 183, and the annular member 184 is similarly spaced from the closing member 181 in the axial direction X to the space 183 side. The air chamber 185 and the space 187 in which the viscous body 26 is disposed are fixed to the inside of the portion 105, and the restraining means is the air chamber 185 communicated with the space 187 through the central hole 186 of the annular member 184. 142 may be configured. When the vibration absorber 101 is provided with the restraining means 142 including the air chamber 185, as shown in FIG. 22, one or more through holes 188 that allow the gaps 25 and 108 and the space 187 to communicate with each other are formed in the cylindrical portion 106. It may be provided at the one end portion 105.

  The volume of the air chamber 185 is decreased by increasing or decreasing the internal pressure of the viscous body 26 due to the movement of the long body 22 relative to the long bodies 21 and 102 in the axial direction X, and the volume of the air chamber 185 increases or decreases. Thus, the increase and decrease of the internal pressure of the viscous body 26 due to the advance and retreat of the long body 22 with respect to the inside of the long body 21 and the advance and retreat of the long body 102 with respect to the inside of the long body 22 are suppressed. In the vibration absorber 7, an air chamber similar to the air chamber 185 may be formed inside the other end side 112 of the cylindrical portion 38, and the suppression unit 142 may be configured with such an air chamber.

  Further, as shown in FIG. 22, a filling hole 191 with a stopper is provided in the other end portion 29 of the cylindrical portion 36, and the inside of the long body 21 or the like through the filling hole 191 before or after installation in the wall space 6. After filling the viscous body 26, the filling hole 191 may be closed with a stopper. In order to form the air chamber 185, the pair of mounting plate members 32 and 152 are paired with the pair of mounting plate members 31 and 151 in a state where the lid member 176 is not fitted between the cylindrical portion 38 and the cylindrical body 174. The absorber 101 is obliquely or upright so as to be positioned above the upper side, and the viscous body 26 is filled into the long body 21 and the like, and after the filling, the lid member is interposed between the cylindrical portion 38 and the cylindrical body 174. 176 may be fitted.

Even after the fitting, the filling of the viscous body 26 into the elongated body 21 through the filling hole 191 is continued, and the air discharge hole is closed after the viscous body 26 is fully filled in the cylindrical portion 38. Further, the viscous body 26 is filled into the cylindrical portion 38 through the air discharge hole, and the air discharge hole is closed after the viscous body 26 is filled in the entire cylindrical portion 38. You may do it.

  Further, as shown in FIG. 22, each of the mounting plate members 31 and 32 has tongues 193 and 194 having through holes 192 for suspending the vibration absorber 101 during transportation, installation, temporary fixing, etc. of the vibration absorber 101. You may have.

  Further, in the vibration absorber 201, a disc-shaped closing member 232 is fixed inside the other end portion 231 of the cylindrical portion 214 to define the inside of the cylindrical portion 214 into a closed space 233 and a space 234, and the closing member 232. The annular member 235 is fixed to the inside of the other end 231 of the cylindrical portion 214 on the space 234 side in the axial direction X, and an air chamber 236 is formed through the central hole 237 of the annular member 235. The suppression means 142 may be configured by the air chamber 236 communicated with the gap 217 or the like. Such restraining means 142 is also formed inside the long body 202 and has an air chamber 236 that reduces the volume by increasing / decreasing the internal pressure of the viscous body 26, so that the inside of each of the long bodies 21 and 102 is reduced. The increase and decrease of the internal pressure of the viscous body 26 due to the advance and retreat of the long bodies 22 and 202 are suppressed. The vibration absorber 201 may be configured to include the suppression unit 142 including the above-described flexible partition wall 145 or the compressible body 148 instead of or together with the suppression unit 142 including the air chamber 236.

  In the vibration absorber 201, it is not necessary to provide the through-hole 188 in the one end portion 105 of the cylindrical portion 106. However, if such a through-hole 188 is provided in the one end portion 105, the viscous body 26 through the filling hole 191 is not provided. When filling the vibration absorber 201, the long body 102 can be quickly filled.

  The above-described vibration absorber 201 is shown in FIG. 5 in the same manner as the vibration absorbers 7 and 101, with the wide mounting surfaces 61 and 62 of both the mounting plate members 31 and 32 arranged parallel to the surface of the wall space 6. It is connected to the lower horizontal member 5 via the connecting means 65 and to the upper horizontal member 4 via the connecting means 66, and is used in the damping wall structure 1 instead of the vibration absorber 7 or 101.

  In the damping wall structure 1 provided with the vibration absorber 201, the effect can be obtained in the same manner as the above-described damping wall structure 1 provided with the vibration absorber 7 or 101, and the long bodies 21 and 102 caused by an earthquake or the like can be obtained. Due to the relative movement of the long bodies 22 and 202 in the axial direction X, in addition to the viscous body 26 disposed in the gaps 25 and 108, the viscous body 26 disposed in the gap 217 also causes viscous shear deformation. As a result of absorbing the relative vibration energy, the vibration due to the earthquake of the building or the like can be attenuated even earlier, and in the vibration absorber 201, the length of each of the mounting plate members 31 and 32 is the same as that of the vibration absorbers 7 and 101. Adherence to the scales 21, 22, 102, and 202 can be further strengthened, and each of the mounting plate members 31 and 32 can be detached from the long bodies 21, 22, 102, and 202 after long-term use. Thing On that we can avoid, because it comprises a mounting plate member 151 and 152, the flexural strength of the attaching plate members 31 and 32 are increased.

  In the vibration absorber 201, the cylindrical portions 36, 38, 106, and 214 of the long bodies 21, 22, 102, and 202 are sufficiently strong in strength, regardless of the thicknesses d1, d2, and d3, and In addition, it is possible to provide the vibration absorber 201 having a weight and a diameter corresponding to the magnitude of the generated damping force, and to efficiently and quickly heat the heat generated in the viscous body 26 to the long bodies 21, 22, It is possible to escape through the respective cylindrical portions 36, 38, 106 and 214 of 102 and 202 to eliminate the temperature rise of the viscous body 26 itself and to generate an intended damping force. Even when the scale members 22 and 202 are moved in the relative axial direction X, no large pressure fluctuation is generated in the viscous body 26, so that vibrations caused by earthquakes such as buildings can be efficiently damped.

  In the above-described vibration absorbers 7, 101 and 201, the mounting plate members 31 and 32 are fitted into the slits 43 and 46 to form the respective mounting means. Instead, for example, as shown in FIGS. Each attachment means may be configured using a collar member or a lid member, in this example, lid members 241 and 242.

  That is, in the vibration absorber 101 shown in FIGS. 24 and 25, one attachment means is provided on each of the other end portion 29 of the cylindrical portion 36 of the long body 21 and one end portion 105 of the cylindrical portion 106 of the long body 102. The cover member 241 is fixed, and the attachment plate member 31 is fixed to the cover member 241 by welding or the like, and the other attachment means is welded to one end 30 of the cylindrical portion 38 of the long body 22. And a mounting plate member 32 fixed to the lid member 242, and the mounting plate member 31 is fixed to the lid member 241 and the other end 29 of the elongated body 21 and The attachment plate member 32 is fixed to the lid member 242 and fixed to the one end portion 30 of the long body 22.

  In addition, in the vibration absorber 101 shown in FIGS. 26 and 27, one attachment means is fixed to the lid member 241 with a bolt 243 in addition to the lid member 241 and the attachment plate member 31, and the attachment plate member 31 is welded. In addition to the lid member 242 and the mounting plate member 32, the other mounting means is fixed to the lid member 242 with bolts 245 and the mounting plate member 32 is welded. The attachment plate member 31 is fixed to the lid member 241 via the flange member 244 and the bolt 243 so that the other end portion 29 of the long body 21 and the long body 102 are fixed. The attachment plate member 32 is fixed to the lid member 242 via the flange member 246 and the bolt 245 and is fixed to the one end portion 30 of the long body 22.

  Further, in the vibration absorber 101 shown in FIGS. 28 and 29, one attachment means is fixed to the attachment plate member 31 and the flange member 244 by welding or the like in addition to the lid member 241, the attachment plate member 31 and the flange member 244. In addition to the lid member 242, the mounting plate member 32, and the flange member 246, the other mounting means is a mounting plate fixed to the mounting plate member 32 and the flange member 246 by welding or the like. A member 152 is provided.
