上記の構成によれば、微辰幅の議が生じた齢、 第 1液室と第 2液室の間を液体が 流通することはなく、 第 1液室の内圧 Q ) 力変ィぉ見制き附の第 1開口を通って弾性 ¾Dり膜の厚肉部に伝わるとともに、第 2開口を通つて弾性 り膜の薄肉部に伝わり、 これにより、 厚肉部及ひ育肉部力往復動変形し、 第 1液室の内圧を吸収して '微辰幅の振 動を させる。 大振幅の »が生じて第 1液室の内圧力所定の値になると、 厚肉部及 ひ薄肉部の変形が限界に達し、 液体がオリフィスを通って両液室間を る。 その液 ί«»効果によって大鍵畐の漏を させる。  According to the above configuration, the age at which the controversy arises, the liquid does not flow between the first liquid chamber and the second liquid chamber, and the internal pressure Q) of the first liquid chamber changes. The force is transmitted to the thick part of the elastic membrane through the first opening of the damper, and to the thin part of the elastic membrane through the second opening. Dynamically deforms and absorbs the internal pressure of the first liquid chamber, causing it to vibrate in the width of a small diameter. When a large amplitude »occurs and the internal pressure of the first liquid chamber reaches a predetermined value, the deformation of the thick part and the thin part reaches the limit, and the liquid passes between the two liquid chambers through the orifice. The liquid «« »effect leaks the large key.
上記の構成では、 tiifE複数の第 1リブの頂部と複数の第 2リブの頂部とが変お見制部 材に当接するだけであるから、 弾性 tfc¾Dり膜と對ぉ見制咅附との翻虫面の繊を十分に 小さくすることができる （弾性t^り膜の固 15も変ィ纖賠附に翻虫しているが、 固 は変 ί 見制咅附に固定されていることから異音発生源とはならない)。また、複数の 第 1リブと第 2リブは厚肉部の周りに分散して位置するから、 厚肉部をその周りから均 一な力で支持できて、 厚肉部に偏った力力幼口わるのを防止することができる。 In the above configuration, the top of the plurality of first ribs and the top of the plurality of second ribs are changed. Since it is only in contact with the material, the fibers on the surface of the insect between the elastic tfc film and the countermeasure control can be made sufficiently small. However, it is not a source of abnormal noise because it is fixed to the change control system.) In addition, since the plurality of first ribs and the second ribs are distributed around the thick portion, the thick portion can be supported with a uniform force from around the thick portion, and the force biased to the thick portion can be reduced. It can be prevented from humming.
弾性 t ^Dり膜を第 1液室の内圧の変化に追従変形し付くしすぎると、 辰幅の應 が生じたときに弾性 tt^Oり膜を第 1液室の所望の内圧で変ィ 見制 （変形の制限） するの が困難になり、 液体がオリフィスを通りにくくなるが、 上言 3»成によれば、 弾性飾り 膜の径方向中央側を厚肉部にして岡 I胜を強くしてあるから、 所望の第 1液室の内圧で弾 性仕切り膜を変位規制しゃすくなる。  If the elastic t ^ D film is too deformed to follow the change in the internal pressure of the first liquid chamber, the elastic tt ^ O film will change at the desired internal pressure of the first liquid chamber when the cinnabar width response occurs. It is difficult to control (limit deformation), and it is difficult for the liquid to pass through the orifice. Since the pressure is increased, the displacement of the elastic partition membrane is restricted by the desired internal pressure of the first liquid chamber.

The external force is fitted to the β of the force S cylinder sound 16 and the structure of the pair of control members 17 and 18 force S elastic ti] (This configuration is a configuration corresponding to claim 4). Industrial applicability
本発明によれば、 異音を十分に 威することができ、 しかも、 微辰幅の高周波数の振 動を? βさせ 、液封入式防 $g¾置を衝共することができた。  ADVANTAGE OF THE INVENTION According to the present invention, abnormal noise can be sufficiently exerted, and at the same time, high-frequency vibration with a fine pitch width can be reduced by β, and a liquid-filled type protection device can be used.
また、 嫌己第 1液室内に攪赚が設けられて、 fflfS攪拌 の外周縁と第 1液室の内周 面との間に第 1液室側オリフィス力形成されていると、 上記の効果に加えて、 翻波か ら高周波にわたる広レ、範囲の »を吸収することができる液封入式 S¾ ^置を Wする ことができる。  In addition, if the first liquid chamber side orifice force is formed between the outer peripheral edge of the fflfS agitation and the inner peripheral surface of the first liquid chamber by providing a stirrer in the first liquid chamber, the above effect is obtained. In addition, a liquid-filled S¾ ^ device that can absorb a wide range, ranging from transversal to high frequency, can be used.
