に嵌合するようになっている。BACKGROUND OF THE INVENTION FIG. 6 shows an example of the structure of a conventional elastic support mount 1. As shown in FIG. This elastic support mount 1 is composed of a metal collar 4 that is fixed to a support member 3 such as a vehicle body panel with a bolt 2, and a substantially cylindrical rubber member 5 that is held via the collar 4. The rubber member 5 has a through hole 6 in the center thereof through which the collar 4 is inserted, and its overall height is slightly larger than that of the collar 4. In the installed state, the collar 4 is held in a slightly compressed state between the flange portion 7 at one end of the collar 4 and the support member 3. A bolt 2 is provided approximately at the center of the outer peripheral surface of the rubber member 5.
A bracket fitting groove 8 is recessed around the entire circumference along a plane orthogonal to the bracket, and a peripheral edge 9a of a mounting hole of a plate-shaped bracket 9 provided in, for example, a car stereo is fitted into the groove. There is. That is, the bracket 9 is connected to the rubber member 5.
By being supported by a support member 3 such as a vehicle body panel through the support member 3, transmission of vehicle body photography and the like is prevented. (Refer to Japanese Utility Model Application Publication No. 59-22343) Problems to be Solved by the Invention The bracket fitting groove 8 in the rubber member 5 is slightly smaller than the plate thickness depending on the plate thickness of the bracket 9. It is formed into a rectangular cross-section with a width, and is adapted to fit relatively tightly with the bracket 9.
従って、プラケツト９の板厚が異なる場合には、嵌め込
むことが困難となシ、あるいは緩みを生じてしまうため
、同一の弾性支持マウント１を使用することができない
。ま念ボルト２軸方向についてのばね定数とりわけ変位
が小さい領域でのばね定数を十分に小さく設定すること
ができず、防振性能の点で同改善すべき余地がある。Therefore, if the thickness of the brackets 9 is different, the same elastic support mount 1 cannot be used because it will be difficult to fit or the brackets will come loose. It is impossible to set the spring constant in the two axial directions of the bolt sufficiently small, especially in the region where the displacement is small, and there is room for improvement in terms of vibration damping performance.
問題点を解決するための手段
この発明は上記の問題点を解決するために、プラケツト
嵌合溝の底部に、該嵌合溝の開口幅よシもボルト軸方向
に拡大した空隙部を形成したことを特徴としている。Means for Solving the Problems In order to solve the above-mentioned problems, the present invention forms a gap at the bottom of the bracket fitting groove which is larger in the bolt axial direction than the opening width of the fitting groove. It is characterized by
作用
上記のように空隙部を設けることによって、プラケツト
嵌合溝の開口部付近のみがプラケツトに圧接して該プラ
ケツトを挾持する形となる。そのため、プラケツトの板
厚が多少異なっても、これを許容して嵌合可能となる。Function: By providing the void as described above, only the area near the opening of the bracket fitting groove comes into pressure contact with the bracket and clamps the bracket. Therefore, even if the plate thicknesses of the brackets differ somewhat, this can be tolerated and they can be fitted together.
また、変位が小さい領域でのばね定数が小さくなる。Moreover, the spring constant becomes small in a region where the displacement is small.
実施例
第１図はこの発明に係る弾性支持マウント１の一実施例
を示しており、上述した従来例と同一部分には同一符号
を付しである。Embodiment FIG. 1 shows an embodiment of an elastic support mount 1 according to the present invention, in which the same parts as in the conventional example described above are given the same reference numerals.
すなわち、この弾性支持マウント１のゴム部材５には、
外周面略中央部に全周に亘ってプラケツト嵌合溝８が凹
設されているが、このプラケツト嵌合溝８の底部に、断
面略円形をなす空隙部１１が全周に亘って形成されてい

よりもボルト２の軸方向に拡大した形状となっている。That is, the rubber member 5 of this elastic support mount 1 has
A bracket fitting groove 8 is recessed around the entire circumference approximately at the center of the outer peripheral surface, and a gap 11 having a substantially circular cross section is formed at the bottom of the bracket fitting groove 8 over the entire circumference. ing. This gap 11 has an opening width t of the bracket fitting groove 8.
The shape is expanded in the axial direction of the bolt 2.
従って、プラケツト９の取付孔周縁部９ａが嵌合した状
態では、第２図、第３図に示すようにプラケツト嵌合溝
８の開口部付近のみがプラケツト９を両面から挾持する
形となる。そのため、プラケツト９の板厚が比較的薄い

うになり、従来品に比べて変位が小さい領域でのばね定
数を十分に小さくすることができる。この結果、従来の
ものに比べて一層優れた防振効果が得られる。Therefore, when the peripheral edge 9a of the mounting hole of the bracket 9 is fitted, only the vicinity of the opening of the bracket fitting groove 8 will hold the bracket 9 from both sides, as shown in FIGS. 2 and 3. Therefore, even if the thickness of the bracket 9 is relatively thin (Fig. 2), if it is relatively thick (Fig. 3).
Even if there are brackets 9 of different thicknesses, the same type of elastic support mount 1 can be used. Since the tip of the bracket 9 is separated from the rubber member 5 due to the existence of the cavity 11, the load-deflection characteristics in the two axial directions of the bolt are as shown in Fig. 4, and the displacement is smaller than that of the conventional product. The spring constant can be made sufficiently small in the region where is small. As a result, an even better vibration damping effect can be obtained compared to the conventional one.

数を更に小さくすることができる。Next, Figure 5 shows a different embodiment of the present invention, in which a cavity 11 is also provided at the bottom of the bracket fitting groove 8. Particularly in this embodiment, both end surfaces 12 and 13 that come into pressure contact with the flange portion 7 and the support member 3 are each formed into a gentle conical surface, and large diameter portions 14 are provided at both ends of the through hole 6, respectively. The large diameter portion 14 is arranged so as not to contact the outer circumferential surface of the collar 4. Therefore, the outer circumferential portion of the rubber member 5 that clamps the bracket 9 can be relatively freely displaced in the axial direction of the bolt, thereby making it possible to further reduce the spring constant.
尚、プラケツト嵌合溝８は、ゴム部材５の成形の際に型
成形されるが、上記のように空隙部１１を形成する場合
には、プラケツト嵌合溝８に対応する部分の金型先端部
が厚肉となシ、金型強度が高くなるという副次的効果も
ある。The bracket fitting groove 8 is molded when the rubber member 5 is molded, but when forming the cavity 11 as described above, the tip of the mold corresponding to the bracket fitting groove 8 is formed. There is also the side effect of increasing the strength of the mold because the part is thicker.
また上記実施例では、ゴム部材５を一体に成形している
が、例えばプラケツト嵌合溝８に沿って２分割して成形
することも可能であるのは言うまでもない。Further, in the above embodiment, the rubber member 5 is integrally molded, but it goes without saying that it is also possible to mold it in two parts along the bracket fitting groove 8, for example.

つ優れた防振効果が得られる。Effects of the Invention As is clear from the above explanation, according to the elastic support mount according to the present invention, the same elastic support mount can be applied to brackets with slightly different plate thicknesses, which is advantageous in parts management and assembly processes. . Further, since the spring constant can be set small in a region where displacement is small, an excellent vibration damping effect can be obtained while suppressing excessive displacement.
