ゴム３０それ自体の座屈が起こりにくくなる。Therefore, the shear spring rubber 30 of the fluid-filled mount 1
Since one or more annular protrusions 32 are integrally formed concentrically with the mount 1 on the inner wall 31 of the mount 1, in other words, one or more annular protrusions 32 are concentrically formed with the so-called axially symmetrical fluid-filled mount 1.・This is also axially symmetrical with shear spring rubber 3
Since it is formed integrally with the inner wall 31 of the mount 1, as the load increases, the annular protrusion 32 suppresses the reaction of the mount 1 in the radial direction as shown in FIG. 2 by its rib-like reinforcing action. However, as a result, expansion and contraction of the diameters of the respective annular protrusions 32 are suppressed, thereby making it difficult for the chef spring rubber 30 itself to buckle.
故にシェアスプリングゴム３０の座屈限界が向上し、以
って高荷重に対しても有効に剛え得ることとなる。Therefore, the buckling limit of the shear spring rubber 30 is improved, so that it can effectively withstand high loads.

ことができる。Therefore, if one or more annular protrusions 32 are formed axially symmetrically, the displacement-load characteristics shown by the solid line in FIG. 3 can be obtained. That is, the buckling limit can be improved using the same material without changing the material of the shear spring rubber 30 itself.

At this time, as the fluid is stirred, the protrusion 33...
・As a result of the fluid resistance to the shear spring rubber 3
Since the resonance of the shear spring rubber 30 itself is suppressed, the high frequency vibration directly transmitted to the cylindrical body 11 of the base member 10 via the shear spring rubber 30 can be effectively reduced.
