Japanese Patent Laid-Open No. 2001-200885

前記能動型制振器では、マウント弾性体１１３の内側にマス金具１１７を配置した構成になっており、従来の装置では、このように弾性部材の内側に質量部材を配置する構造になっていた。
しかし、このような構造では、質量部材の大きさ（質量）が弾性部材の形状に制約されることになる。これでは、制振できる周波数帯も限定されることになってしまう。
そこで、本発明は、前述の問題に鑑みてなされたものであり、質量部材の質量の選択の自由度、特に質量を大きくする自由度が高い防振支持装置の提供を目的とする。 The active vibration damper has a configuration in which the mass metal fitting 117 is arranged inside the mount elastic body 113, and the conventional device has a structure in which the mass member is arranged inside the elastic member in this way. .

また、本発明に係る防振支持装置は、前記複数の弾性支持部材のうち、前記振動体を支持する弾性支持部材の支持中心と、前記支持体に固定される弾性支持部材の固定中心とが一致するように前記弾性支持部材を配置しつつ、前記複数の弾性支持部材を、直線上に、かつそれぞれが等間隔になるように配置する。 An anti-vibration support device according to the present invention is provided between a vibrating body and a support body, and includes a plurality of elastic support members that are fixed to either the vibrating body or the support body. member, and at least one elastic support member for supporting said vibrating body, and at least one elastic support member is fixed to the support, is composed of, it holds the previous SL plurality of elastic support members therein comprising a holding member which constitutes the mass member Te.
The vibration isolating support device according to the present invention includes a support center of an elastic support member that supports the vibrating body and a fixed center of an elastic support member that is fixed to the support body among the plurality of elastic support members. The plurality of elastic support members are arranged on a straight line so as to be equidistant from each other while arranging the elastic support members so as to coincide with each other.

本発明によれば、質量部材としての保持部材が弾性支持部材を内部に保持することで、保持部材の形状の自由度を高くすることができ、これにより、保持部材の質量の選択の自由度を高くすることができる。   According to the present invention, since the holding member as the mass member holds the elastic support member inside, the degree of freedom of the shape of the holding member can be increased, and thereby the degree of freedom of selection of the mass of the holding member. Can be high.

本発明を実施するための最良の形態（以下、実施の形態という。）を図面を参照しながら詳細に説明する。
図１及び図２は、本発明を適用した第１の実施の形態の防振支持装置を示す。
図１に示すように、略長方形の略直方体の本体部２に、３個の防振体３，４，５を備えている。第１乃至第３の防振体３，４，５は、略円柱形状をなしており、本体部２に一側面から反対側の他側面に貫通するようにして配置されている。ここで、本体部２は、質量部材とされる保持部材を構成し、防振体３，４，５は弾性支持部材を構成している。 The best mode for carrying out the present invention (hereinafter referred to as an embodiment) will be described in detail with reference to the drawings.
1 and 2 show a vibration isolating support apparatus according to a first embodiment to which the present invention is applied.
As shown in FIG. 1, a substantially rectangular main body 2 having a substantially rectangular parallelepiped shape includes three vibration isolators 3, 4, and 5. The 1st thru | or 3rd vibration isolator 3,4,5 has comprised the substantially columnar shape, and is arrange | positioned so that the main body part 2 may penetrate from the one side surface to the other side surface on the opposite side. Here, the main body 2 constitutes a holding member that is a mass member, and the vibration isolators 3, 4, and 5 constitute elastic support members.

第１乃至第３の防振体３，４，５は、図２に示すように、直線上に、かつそれぞれが等間隔になるように配置されている。具体的には、第１乃至第３の防振体３，４，５は、その中心軸（或いは支持軸）Ｏが平行になるように、かつそれぞれの中心軸Ｏ間の距離が等間隔になるように配置されている。
第１乃至第３の防振体３，４，５は、内筒１１と外筒１２との間で防振部材１３を挟む込む構造となっている。防振部材１３は弾性材によって形成されている。例えば、本体部２に３ヶ所の孔を開けて、その本体部２のそのそれぞれの孔に第１乃至第３の防振体３，４，５が挿入固定されている。 As shown in FIG. 2, the first to third vibration isolator 3, 4, 5 are arranged on a straight line and at equal intervals. Specifically, the first to third vibration isolators 3, 4 and 5 have their central axes (or support shafts) O parallel to each other, and the distances between the central axes O are equally spaced. It is arranged to be.
The first to third vibration isolator 3, 4, 5 has a structure in which the vibration isolating member 13 is sandwiched between the inner cylinder 11 and the outer cylinder 12. The vibration isolation member 13 is formed of an elastic material. For example, three holes are formed in the main body 2, and the first to third vibration isolation bodies 3, 4, 5 are inserted and fixed in the respective holes of the main body 2.

このような防振支持装置において、本体部２において両側に位置されている第１及び第３の防振体３，５で、図示しない支持体又は振動体に固定されている。そして、第１及び第３の防振体３，５で支持体に固定されている場合には、第１及び第３の防振体３，５の間に位置されている第２の防振体４で、図示しない振動体を支持し、第１及び第３の防振体３，５で振動体を支持している場合には、第２の防振体４で図示しない支持体に固定されている。ここで、第１乃至第３の防振体３，４，５の内筒１１にボルト等によって、振動体又は支持体が固定される。また、振動体は、例えばエンジンや変速機を含むパワーユニットであり、支持体は車体側部材である。   In such an anti-vibration support device, the first and third anti-vibration bodies 3 and 5 located on both sides of the main body 2 are fixed to a support body or vibration body (not shown). And when it fixes to a support body with the 1st and 3rd anti-vibration bodies 3 and 5, the 2nd anti-vibration body located between the 1st and 3rd anti-vibration bodies 3 and 5 When the body 4 supports a vibration body (not shown) and the first and third vibration isolation bodies 3 and 5 support the vibration body, the second vibration isolation body 4 is fixed to the support body (not shown). Has been. Here, the vibrating body or the support body is fixed to the inner cylinders 11 of the first to third vibration isolator bodies 3, 4, 5 by bolts or the like. The vibrating body is a power unit including an engine and a transmission, for example, and the support is a vehicle body side member.

前述したように、第１乃至第３の防振体３，４，５は、図２に示すように、直線上に、かつそれぞれが等間隔になるように、本体部２内に配置されている。よって、例えば、第１及び第３の防振体３，５で支持体に固定され、第２の防振体２で振動体を支持している場合を考えると、第１の防振体３と第３の防振体５との中間位置に支持体との固定中心が存在し、第２の防振体４の中心軸Ｏ上に振動体の支持中心が存在することになる。すなわち、支持体との固定中心と振動体の支持中心とが一致している。   As described above, the first to third anti-vibration bodies 3, 4 and 5 are arranged in the main body 2 on a straight line and at equal intervals as shown in FIG. Yes. Therefore, for example, considering the case where the first and third vibration isolator 3 and 5 are fixed to the support and the second vibration isolator 2 supports the vibration body, the first vibration isolator 3. There is a fixed center with the support at an intermediate position between the second vibration isolator 5 and the third vibration isolator 5, and a support center of the vibrator is present on the central axis O of the second vibration isolator 4. That is, the fixed center with the support body and the support center of the vibrating body coincide.

以上のような構成をなす防振支持装置は、第１乃至第３の防振体３，４，５が振動体から支持体への振動を吸収することで、振動体から支持体への振動伝達を抑制している。さらに、本体部２が所定の形状、すなわち所定の質量を有していることで所定の周波数の振動伝達を抑制している。
図３乃至図６は防振支持装置１が振動体としてのパワーユニット１０２を支持している状態を示す。
図３は、斜視図であり、図４は、パワーユニット１０２において防振支持装置１を取り付けた支持部１０２ａ近傍の詳細を示す。図５は、正面図であり、図６は、図５において矢示Ａ−Ａ断面を示す側面図である。
この図３に示すように、支持体（車体側部材）１０１に各防振支持装置１を介してパワーユニット１０２の両側を支持しており、各防振支持装置１において、第１及び第３の防振体３，５に支持体１０１が取り付けられており、かつ第２の防振体４にパワーユニット１０２が取り付けられている。 The anti-vibration support device having the above-described configuration has the first to third anti-vibration bodies 3, 4, and 5 that absorb vibration from the vibration body to the support body, so that the vibration from the vibration body to the support body Transmission is suppressed. Furthermore, vibration transmission at a predetermined frequency is suppressed because the main body 2 has a predetermined shape, that is, a predetermined mass.
3 to 6 show a state in which the vibration isolating support device 1 supports a power unit 102 as a vibrating body.
FIG. 3 is a perspective view, and FIG. 4 shows details of the vicinity of the support portion 102a to which the anti-vibration support device 1 is attached in the power unit 102. FIG. FIG. 5 is a front view, and FIG. 6 is a side view showing an AA cross section in FIG.
As shown in FIG. 3, both sides of the power unit 102 are supported on a support body (vehicle body side member) 101 via each anti-vibration support device 1, and in each anti-vibration support device 1, first and third The support body 101 is attached to the vibration isolation bodies 3 and 5, and the power unit 102 is attached to the second vibration isolation body 4.

具体的には、図５及び図６に示すように、第１乃至第３の防振体３，４，５が水平方向に並ぶように、防振支持装置１を固定部１０１に取り付ける。ここで、第１及び第３の防振体３，５（内筒１１）内に固定用ボルト１１１を挿通しており、その固定ボルト１１１の一端を支持体１０１に直接取り付けて、その固定ボルト１１１の他端を、支持体１０１に固定されている固定用ステー１１２に取り付ける。また、固定用ステー１１２を固定用ボルト１１３により支持体１０１に固定する。そして、防振支持装置１は、第２の防振体２（内筒１１）内に支持部１０２ａに設けた固定用シャフト１０２ｂが挿通されることで、パワーユニット１０２を支持している。   Specifically, as shown in FIGS. 5 and 6, the anti-vibration support device 1 is attached to the fixed portion 101 so that the first to third anti-vibration bodies 3, 4, and 5 are aligned in the horizontal direction. Here, a fixing bolt 111 is inserted into the first and third vibration isolator 3, 5 (inner cylinder 11), and one end of the fixing bolt 111 is directly attached to the support body 101, and the fixing bolt is fixed. The other end of 111 is attached to a fixing stay 112 fixed to the support 101. Further, the fixing stay 112 is fixed to the support body 101 with fixing bolts 113. The anti-vibration support device 1 supports the power unit 102 by inserting a fixing shaft 102b provided on the support portion 102a into the second anti-vibration body 2 (inner cylinder 11).

次に第１の実施の形態における作用及び効果を説明する。
前述したように、第１乃至第３の防振体３，４，５が本体部２を貫通するように取り付けられている。すなわち、第１乃至第３の防振体３，４，５の外周部を覆うように、或いは第１乃至第３の防振体３，４，５を内部に保持するように、本体部２が形成されている。これにより、本体部２の形状の設計自由度は高くなる。よって、質量部材としての本体部２の形状の設計自由度が高いことから、防振支持装置の共振周波数を容易に変化させることができる。例えば、本体部２の形状を大きくする、すなわち本体部２の質量を多くすることができるので、防振支持装置の共振周波数を小さくできる。これにより、低周波数域において、振動体から支持体への振動伝達を抑制することができる。 Next, operations and effects in the first embodiment will be described.
As described above, the first to third vibration isolator 3, 4, 5 is attached so as to penetrate the main body 2. That is, the main body portion 2 so as to cover the outer peripheral portions of the first to third vibration isolators 3, 4, 5 or to hold the first to third vibration isolator 3, 4, 5 inside. Is formed. Thereby, the design freedom of the shape of the main-body part 2 becomes high. Therefore, since the design freedom of the shape of the main body 2 as the mass member is high, the resonance frequency of the vibration isolating support device can be easily changed. For example, since the shape of the main body 2 can be increased, that is, the mass of the main body 2 can be increased, the resonance frequency of the vibration isolating support device can be reduced. Thereby, vibration transmission from the vibrating body to the support body can be suppressed in a low frequency range.

図７はその効果を示す特性図である。この図７に示すように、共振周波数を低周波数側にシフトさせることができ、これにより、これまで振動体から支持体への伝達力が大きかった周波数領域（従来部分の領域）で、当該伝達力を小さくすることができる。
また、複数の防振体３，４，５で振動体及び支持体に固定されているので、防振体３，４，５のレイアウト性を高くすることができる。また、この防振体３，４，５の弾性係数を小さくすることもできる。 FIG. 7 is a characteristic diagram showing the effect. As shown in FIG. 7, the resonance frequency can be shifted to the low frequency side, so that the transmission is performed in the frequency region (region of the conventional part) where the transmission force from the vibrating body to the support body has been large so far. The power can be reduced.
Further, since the vibration isolator 3, 4 and 5 are fixed to the vibration body and the support body, the layout properties of the vibration isolator 3, 4 and 5 can be improved. Further, the elastic modulus of the vibration isolators 3, 4, and 5 can be reduced.

また、前述したように、第１乃至第３の防振体３，４，５は、直線上、かつそれぞれが等間隔に配置されている。すなわち、例えば支持体に固定される第１及び第３の防振体３，５との固定中心と、振動体を支持する第２の防振体２の支持中心とが一致するように、これら防振体３，４，５を配置している。
これにより、防振支持装置は、振動体の振動方向に対して直交する２方向に振動することなく、当該振動体の振動を防振することができる。すなわち、防振支持装置、具体的には本体部２は、振動体の振動方向にのみ確実に防振効果を作用させることができ、振動方向にのみ伝達力（制振した伝達力）を支持体に伝えるようになる。 Further, as described above, the first to third vibration isolators 3, 4, and 5 are arranged on a straight line and at equal intervals. That is, for example, such that the fixed center of the first and third vibration isolator 3 and 5 fixed to the support body and the support center of the second vibration isolator 2 that supports the vibration body coincide with each other. Anti-vibration bodies 3, 4 and 5 are arranged.
Thus, vibration isolation support system, without oscillating in two directions Cartesian with respect to the vibration direction of the vibrating body, it is possible to vibration damping the vibration of the vibrating body. That is, the anti-vibration support device, specifically, the main body 2 can reliably act on the anti-vibration effect only in the vibration direction of the vibrating body and supports the transmission force (damped transmission force) only in the vibration direction. Come to the body.

例えば、第１及び第３の防振体３，５に支持体側が取り付けられ、第２の防振体４に振動体が取り付けられている場合において、図２に示すように第１乃至第３の防振体３，４，５が紙面に垂直方向に配置されている場合に、図示しない振動体からの振動が第２の振動体４に対して平行方向（紙面垂直方向）に入力されたときには、第１乃至第３の防振体３，４，５が直線上に、かつそれぞれ等間隔に配置されていることから、防止支持装置は、他の２方向、すなわち、図２において上下方向及び左右方向に振動することなく、当該平行方向に入力される振動を防振することができる。   For example, in the case where the support body side is attached to the first and third vibration isolator 3 and 5 and the vibration body is attached to the second vibration isolator 4, the first to third as shown in FIG. When vibration isolators 3, 4 and 5 are arranged in a direction perpendicular to the paper surface, vibration from a vibration body (not shown) is input in a direction parallel to the second vibration body 4 (perpendicular to the paper surface). In some cases, the first to third vibration isolators 3, 4 and 5 are arranged in a straight line and at equal intervals, so that the prevention support device has two other directions, that is, the vertical direction in FIG. In addition, vibrations input in the parallel direction can be prevented without vibration in the left-right direction.

例えば、第１乃至第３の防振体３，４，５の外周部を本体部２で覆うことだけに、或いは第１乃至第３の防振体３，４，５を本体部２の内部で保持することだけに着目すれば、第１乃至第３の防振体３，４，５をどのような配置でもよい。しかし、第１乃至第３の防振体３，４，５を任意に配置してしまうと、防振支持装置は、振動体の振動方向以外の方向にも振動してしまうことになる。   For example, only covering the outer periphery of the first to third vibration isolator 3, 4, 5 with the main body 2, or the first to third vibration isolator 3, 4, 5 inside the main body 2. If only focusing on holding, the first to third vibration isolators 3, 4 and 5 may be arranged in any manner. However, if the first to third vibration isolation bodies 3, 4 and 5 are arbitrarily arranged, the vibration isolation support device will vibrate in directions other than the vibration direction of the vibration body.

しかし、前述したように、第１乃至第３の防振体３，４，５を直線上に、かつそれぞれ等間隔に配置することで、振動体の振動方向に対して直交する２方向に振動することなく、当該振動体の振動を防振することができるようになる。
次に第２の実施の形態を説明する。
前記第１の実施の形態では、本体部２が略長方形の略直方体であり、その本体部２に直線上であり、かつそれぞれが等間隔になるように第１乃至第３の防振体３，４，５を配置した防振支持装置を説明した。この第２の実施の形態は、図８に示すように、略正方形の略直方体２２に、第１乃至第４の防振体２３，２４，２５，２６を備えた防振支持装置である。 However, as described above, the first to third isolator 3,4,5 a straight line, and by arranging at regular intervals, respectively, in two directions Cartesian with respect to the vibration direction of the vibrating body The vibration of the vibrating body can be prevented without vibration.
Next, a second embodiment will be described.
In the first embodiment, the main body 2 is a substantially rectangular parallelepiped, and is straight to the main body 2 and the first to third vibration isolators 3 are arranged at equal intervals. , 4 and 5 are described. As shown in FIG. 8, the second embodiment is an anti-vibration support device provided with first to fourth anti-vibration bodies 23, 24, 25, and 26 on a substantially square rectangular parallelepiped 22.

この第２の実施の形態の防振支持装置の第１乃至第４の防振体２３，２４，２５，２６の構造は、前記第１の実施の形態の防振支持装置の防振体３，４，５の構造と同じである。この防止支持装置では、本体部２２に４ヶ所の孔を開けて、そのそれぞれの孔に第１乃至第４の防振体２３，２４，２５，２６が挿入固定されている。
ここで、第１の防振体２３と第２の防振体２４とを結ぶ第１の直線Ｘ１と、第３の防振体２５と第４の防振体２６とを結ぶ第２の直線Ｘ２とがそれぞれの中間位置（交点ＸＯ）で交差するように、これら防振体２３，２４，２５，２６を配置している。言い換えれば、第１の防振体２３と第２の防振体２４とを結ぶ第１の直線Ｘ１について対称になるように、第３及び第４の防振体２５，２６を配置している。また、第１乃至第４の防振体２３，２４，２５，２６は、その中心軸（或いは支持軸）Ｏが平行になるように配置されている。 The structure of the first to fourth vibration isolating bodies 23, 24, 25, and 26 of the vibration isolating support device of the second embodiment is the same as that of the vibration isolating support 3 of the vibration isolating support device of the first embodiment. , 4 and 5 are the same. In this prevention support device, four holes are formed in the main body 22, and the first to fourth vibration isolation bodies 23, 24, 25, and 26 are inserted and fixed in the respective holes.
Here, the first straight line X1 connecting the first vibration isolator 23 and the second vibration isolator 24, and the second straight line connecting the third vibration isolator 25 and the fourth vibration isolator 26. These anti-vibration bodies 23, 24, 25, and 26 are arranged so that X2 intersects at each intermediate position (intersection XO). In other words, the third and fourth vibration isolators 25 and 26 are arranged so as to be symmetric with respect to the first straight line X1 connecting the first vibration isolator 23 and the second vibration isolator 24. . Further, the first to fourth vibration isolator 23, 24, 25, 26 are arranged so that their central axes (or support axes) O are parallel.

そして、第１及び第２の防振体２３，２４で、図示しない支持体又は振動体に固定されている。そして、第１及び第２の防振体２３，２４で支持体に固定されている場合には、第３及び第４の防振体２５，２６で、図示しない振動体を支持し、第１及び第２の防振体２３，２４で振動体を支持している場合には、第３及び第４の防振体２５，２６で、図示しない支持体に固定されている。
よって、例えば、第１及び第２の防振体２３，２４で支持体を支持し、第３及び第４の防振体２５，２６で振動体を支持している場合を考えると、第１の防振体２３と第２の防振体２４との中間位置に支持体の支持中心が存在し、第３の防振体２５と第４の防振体２６との中間位置に振動体の支持中心が存在することになる。そして、このとき、支持体との固定中心と振動体の支持中心とが一致する。 The first and second vibration isolator bodies 23 and 24 are fixed to a support body or vibration body (not shown). When the first and second vibration isolation bodies 23 and 24 are fixed to the support body, the third and fourth vibration isolation bodies 25 and 26 support the vibration body (not shown), and When the vibrating body is supported by the second vibration isolator 23 and 24, the third and fourth vibration isolator 25 and 26 are fixed to a support body (not shown).
Therefore, for example, considering the case where the support body is supported by the first and second vibration isolation bodies 23, 24 and the vibration body is supported by the third and fourth vibration isolation bodies 25, 26, the first The support center of the support exists at an intermediate position between the vibration isolator 23 and the second vibration isolator 24, and the vibration body is located at an intermediate position between the third vibration isolator 25 and the fourth vibration isolator 26. There will be a support center. At this time, the fixed center with the support and the support center of the vibrating body coincide.

次に第２の実施の形態における作用及び効果を説明する。
この第２の実施の形態でも同様に、前記第１の実施の形態における作用及び効果を得ることができる。
すなわち、前述したように、第１乃至第４の防振体２３，２４，２５，２６が本体部２２に貫通するように取り付けられている。すなわち、第１乃至第４の防振体２３，２４，２５，２６の外周部を覆うように本体部２２が形成されている。これにより、本体部２１の形状の設計自由度は高くなる。よって、質量部材としての本体部２２の形状の設計自由度が高いことから、防振支持装置の共振周波数を容易に変化させることができる。例えば、本体部２２の形状を大きくする、すなわち本体部２２の質量を多くすることができるので、防振支持装置の共振周波数を小さくできる。これにより、低周波数域において、振動体から支持体への振動伝達を抑制することができる。 Next, operations and effects in the second embodiment will be described.
Similarly, in the second embodiment, the operation and effect of the first embodiment can be obtained.
That is, as described above, the first to fourth vibration isolator 23, 24, 25, 26 is attached so as to penetrate the main body 22. That is, the main body 22 is formed so as to cover the outer peripheral portions of the first to fourth vibration isolator 23, 24, 25, 26. Thereby, the design freedom of the shape of the main-body part 21 becomes high. Therefore, since the design freedom of the shape of the main body portion 22 as the mass member is high, the resonance frequency of the vibration isolating support device can be easily changed. For example, since the shape of the main body portion 22 can be increased, that is, the mass of the main body portion 22 can be increased, the resonance frequency of the vibration isolating support device can be reduced. Thereby, vibration transmission from the vibrating body to the support body can be suppressed in a low frequency range.

また、複数の防振体２３，２４，２５，２６で振動体及び支持体に固定されているので、防振体２３，２４，２５，２６のレイアウト性を高くすることができる。また、この防振体２３，２４，２５，２６の弾性係数を小さくすることもできる。
また、前述したように、第１の防振体２３と第２の防振体２４とを結ぶ第１の直線Ｘ１と、第３の防振体２５と第４の防振体２６とを結ぶ第２の直線Ｘ２とがそれぞれの中間位置（交点ＸＯ）で交差するように、これら防振体２３，２４，２５，２６を配置している。 Moreover, since the vibration isolator 23, 24, 25, 26 is fixed to the vibration body and the support body, the layout of the vibration isolator 23, 24, 25, 26 can be improved. Further, the elastic coefficient of the vibration isolator 23, 24, 25, 26 can be reduced.
Further, as described above, the first straight line X1 connecting the first vibration isolator 23 and the second vibration isolator 24, and the third vibration isolator 25 and the fourth vibration isolator 26 are connected. These vibration isolators 23, 24, 25, and 26 are arranged so that the second straight line X2 intersects at each intermediate position (intersection XO).

これにより、防振支持装置は、振動体の振動方向に対して直交する２方向に振動することなく、当該振動体の振動を防振することができる。すなわち、防振支持装置、具体的には本体部２２は、振動体の振動方向にのみ確実に防振効果を作用させることができる。
例えば、前記第１の実施の形態では、３個の防振体３，４，５を、直線上に、かつそれぞれが等間隔になるように配置している。しかし、３個の防振体をそのように直線上に、かつそれぞれが等間隔になるように配置できない場合がある。例えば、図８の防振支持装置の構造が、第１、第２及び第３の防振体２３，２４，２５からなる構造になると仮定すると、３個の防振体２３，２４，２５は、直線上に位置することなく、またそれぞれが等間隔に位置されないことになる。例えば、振動体或いは支持体の構造により、防振支持装置側がそのような構造になってしまう場合が考えられる。防振支持装置がこのような構造になった場合、防振支持装置は、振動体の振動方向に対して直交する２方向にも振動してしまう場合がある。 Thus, vibration isolation support system, without oscillating in two directions Cartesian with respect to the vibration direction of the vibrating body, it is possible to vibration damping the vibration of the vibrating body. That is, the anti-vibration support device, specifically, the main body 22 can reliably exert the anti-vibration effect only in the vibration direction of the vibrating body.
For example, in the first embodiment, the three vibration isolators 3, 4, and 5 are arranged on a straight line so that each is equally spaced. However, there are cases where the three vibration isolators cannot be arranged on such a straight line and at equal intervals. For example, assuming that the structure of the anti-vibration support device of FIG. 8 is a structure including first, second and third anti-vibration bodies 23, 24 and 25, the three anti-vibration bodies 23, 24 and 25 are These are not located on a straight line and are not located at regular intervals. For example, there may be a case where the vibration-proof support device side has such a structure due to the structure of the vibrating body or the support. If vibration isolation support system has become such a structure, vibration-damping support device may be in two directions Cartesian with respect to the vibration direction of the vibrating body will vibrate.

これに対して、本発明を適用することで、第１の防振体２３と第２の防振体２４とを結ぶ第１の直線Ｘ１について、第３の防振体２５と対称となる位置に第４の防振体２６を配置する構造にすることで、防振支持装置は、前記第１の実施の形態のように３個の防振体３，４，５だけを備えた防振支持装置と同様な効果を得ることができる。
以上、本発明の実施の形態について説明した。しかし、本発明は、前述の実施の形態として実現されることに限定されるものではない。 On the other hand, by applying the present invention, the first straight line X1 connecting the first vibration isolator 23 and the second vibration isolator 24 is symmetrical with the third vibration isolator 25. By adopting a structure in which the fourth vibration isolator 26 is disposed in the anti-vibration support device, the anti-vibration support device includes only three anti-vibration bodies 3, 4, and 5 as in the first embodiment. The same effect as the support device can be obtained.
The embodiment of the present invention has been described above. However, the present invention is not limited to being realized as the above-described embodiment.

すなわち、前記第１の実施の形態では、第１乃至第３の防振体３，４，５を本体部２に備えた場合を説明している。しかし、これに限定されないことはいうまでもない。図９に示すように、第１乃至第３の防振体３３，３４，３５を個別の部材となるように構成してもよい。
この図９に示すように、略正方形の略直方体の本体部３２に第２の防振体３４を設ける。また、第１及び第３の防振体３３，３５は、内筒４１と外筒４２とで防振部材４３を挟み込む構造としつつも、外筒４２の両端部４２ａ，４２ａで本体部４３にボルト４４で固定されるようにする。このように、第１乃至第３の防振体３３，３４，３５は着脱可能な構造となる。 That is, in the first embodiment, the case where the main body portion 2 includes the first to third vibration isolator 3, 4, 5 is described. However, it goes without saying that the present invention is not limited to this. As shown in FIG. 9, you may comprise the 1st thru | or 3rd vibration isolator 33,34,35 so that it may become a separate member.
As shown in FIG. 9, a second vibration isolator 34 is provided on a main body 32 that is a substantially rectangular parallelepiped. Further, the first and third vibration isolator 33 and 35 have a structure in which the vibration isolating member 43 is sandwiched between the inner cylinder 41 and the outer cylinder 42, but the both ends 42 a and 42 a of the outer cylinder 42 are attached to the main body 43. It is fixed with bolts 44. In this way, the first to third vibration isolator 33, 34, 35 has a detachable structure.

具体的には、図１２及び図１３に示すように、第１乃至第３の防振体３，４，５が垂直方向（鉛直方向）に並ぶように、防振支持装置１を固定部１３１に取り付ける。ここで、第１及び第３の防振体３，５（内筒１１）内に固定用ボルト１１１を挿通して、その固定ボルト１１１の両端を支持体１３１に固定されている固定用ステー１１２に取り付ける。固定用ステー１１２を固定用ボルト１１３により支持体１２１の横側面に固定する。また、振動体１３２の支持部１３２ａの一端にはステー部１３２ｂが設けてある。第２の防振体２（内筒１１）内を固定用ボルト１１１を挿通して、その固定ボルト１１１の両端にこのステー部１３２ｂを取り付ける。 Moreover, the form as shown in FIG.12 and FIG.13 may be sufficient. 12 is a front view, and FIG. 13 is a side view showing a cross section taken along the line CC in FIG.
Specifically, as shown in FIGS. 12 and 13, the anti-vibration support device 1 is fixed to the fixed portion 131 so that the first to third anti-vibration bodies 3, 4, 5 are aligned in the vertical direction (vertical direction). Attach to. Here, the fixing bolt 111 is inserted into the first and third vibration isolator 3, 5 (inner cylinder 11), and both ends of the fixing bolt 111 are fixed to the support 131. Attach to.

また、前記第１の実施の形態では、防振支持装置が３個の防振体３，４，５を備え、また、前記第２の実施の形態では、防振支持装置が４個の防振体２３，２４，２５，２６を備えた場合を説明した。しかし、防振支持部材である防振体を数はこれらの数に限定されるものではない。すなわち、同様な効果を得る限り、すなわち振動体を支持する防振体の支持中心と、支持体に固定される防振体の支持中心とが一致するようにこれら防振体を配置している限り、防振支持装置が異なる個数の防振体を備えてもよい。   In the first embodiment, the anti-vibration support device includes the three anti-vibration bodies 3, 4, and 5. In the second embodiment, the anti-vibration support device includes the four anti-vibration support devices. The case where the vibrators 23, 24, 25, and 26 are provided has been described.
