配置する。尚、第２図においで、ｈ、はゴムパッド本体
１の高さ（厚さの１／２）である。Striped projections 2 are integrally formed on both sides of the rubber pad body 1. In this embodiment, as is clear from FIG. 2, striped protrusions 2m and 2b having two different heights hlth2 are alternately formed, but the invention is not limited to this; Striped protrusions 2 with different heights of two or more stages, such as different stages, four stages, etc.
Any striped protrusion 2 may be used as long as it is formed. In this case, the striped protrusions 2 of the same height are arranged so that they are not adjacent to each other. In addition, in FIG. 2, h is the height (1/2 of the thickness) of the rubber pad main body 1.
また、ゴムパッド本体１の両側面のストライプ状突起２

しかも、上面のストライプ状突起２ａが高い場合には、

さの異なるストライプ状突起２を対にして組み合わせる
。In addition, striped protrusions 2 on both sides of the rubber pad body 1
are formed at symmetrical positions with respect to the rubber pad body 1,
Moreover, when the striped projections 2a on the upper surface are high,
The corresponding striped protrusions 2b on the lower surface are formed low, and conversely, when the striped protrusions 2b on the upper surface are low, the corresponding striped protrusions 2a on the lower surface are formed high, etc.
Striped protrusions 2 of different sizes are combined in pairs.
また、上記実施例ではストライプ状突起２の幅すは同じ

パッドは、非線形的に変化する特性を有する。FIG. 3 is a graph showing the relationship between the compressive displacement (cm) and the compressive load (kg/cm") of the rubber pad. When the tall striped protrusion 2a shown in FIG. 2 is compressed, the compressive load changes along the actual MA. gradually increases and reaches the height h2 of the low striped protrusion 2b.When compression is continued, the striped protrusion 2b is also compressed in addition to the striped protrusion 2a, and the compressive load increases along the actual MB. Then, the height of the rubber pad body 1 is reached.If the compression is continued further, the rubber pad body 1 will be compressed in addition to the striped protrusions 2a and 2b, and the combined compression load will be along the solid line C. Thus, the rubber pad of the present invention has properties that vary non-linearly.
第４図は上記ゴムパッドを床３と機械ベース４との間に
セットした状態を示すもので、この場合、高いストライ
プ状突起２ａが低いストライプ状突起２ｂとほぼ同じ高
さになるように圧縮した状態でセットする。Figure 4 shows the rubber pad set between the floor 3 and the machine base 4. In this case, the rubber pad is compressed so that the high striped protrusions 2a are approximately the same height as the low striped protrusions 2b. Set in condition.
この状態で、高いストライプ状突起２ａは、既に荷重を
受けて変形しても、低いストライプ状突起２ｂは未だ荷
重を受けておらず、ゴムパッド本体１中の応力は不均一
に分布する。In this state, even if the high striped protrusions 2a have already been deformed under load, the low striped protrusions 2b have not yet received any load, and the stress in the rubber pad body 1 is unevenly distributed.
従°って、圧縮や剪断に対してゴムパッド本体１中を応
力等が斜めに伝播するので、振動や衝撃も分散され、吸
収され易い。Therefore, stress and the like propagate diagonally through the rubber pad main body 1 in response to compression and shearing, so vibrations and shocks are also easily dispersed and absorbed.

の伝播は減衰される。In addition, in this set state, when the supported machine vibrates, the high striped protrusions 2a, which have already been compressed, elastically return while following the upward vibration, and conversely, the downward vibration For an amplitude of , the low striped projections 2b are elastically compressed, so that the propagation of the vibrations to the floor 3 is damped.
尚、上記実施例では、ストライプ状突起２をゴムパッド

うに、ゴムパッド本体１の片側面にのみストライプ状突
起を形成してもよい。In the above embodiment, the striped protrusions 2 are formed on both sides of the rubber pad body 1, but the rubber pad of the present invention is not limited to this, and as shown in FIG. Striped protrusions may be formed only on one side of the plate.

果的である。L Effect of invention 1 (1) Since the protrusions are formed in a stripe shape, deformation due to vibration in the longitudinal direction of the stripe is prevented.
It is effective as a vibration-proof rubber pad for supported objects that do not like displacement. This is particularly effective in cases such as trains where the spacing between tracks is fixed and deformation in the direction of changing this spacing is not allowed.
（２）ストライプ状突起の高さを数段階に変化させたの
