る。2 and 3 show a conventional cushion member 10 for supporting a compressor. The cushion member 10 supports the compressor 1 of the refrigerator via legs 2 provided at several places. The cushion member 10 is made of an elastic body such as rubber and has a hollow tubular shape as a whole. A flange 12 is provided on the top portion, and an instruction portion 16 which is a shoulder portion is provided below the flange 12 via a neck portion 14. Below the support portion 16, there is a tubular body portion 18 that bulges outward in the radial direction in an arcuate cross-section, and at the lower end of the body portion 18, an annular base portion 20 having a small diameter and extending vertically is provided. There is. The shaft portion of the bolt 3 having the flat plate portion 4 at the lower end is inserted into the compressor base 5 from below, and the flat plate portion 4 is spot-welded to the compressor base 5, so that the bolt 3 is erected and fixed. . The cushion member 10 is fitted to the bolt 3, and the cushion washer 7 is pushed into the constricted portion of the upper portion of the bolt 3 to prevent the cushion member 10 from being pulled out upward. As a result, the cushion member 10 is positioned. The tip 6 of the support leg 2 of the compressor 1 is bifurcated and fits into the constricted portion 14 of the cushion member 10. In this way, the load of the compressor 1 is supported by the support portion 16.

Have the same thickness t 2 . If the wall thicknesses t 1 and t 2 are reduced to reduce the spring constant, a collapse phenomenon occurs in the body portion 18 due to the load of the compressor. Further, if the wall thicknesses t 1 and t 2 are increased in order to prevent such a crushing phenomenon, the spring constant does not become sufficiently small and the vibration damping effect becomes small.

より小さくしたものである。A cushion member for supporting a compressor according to a first aspect of the present invention has a hollow shape and is interposed between a compressor base and a compressor mounted on the compressor base. For supporting a compressor, which includes a supporting portion for supporting, a tubular body portion that is continuously provided below the supporting portion and bulges outward in the radial direction, and a small-diameter annular base portion that is continuously provided below the body portion. In the cushion member, the thickness of the annular base portion is smaller than that of the body portion.

小さくして、所期の防振効果を上げることができる。[Operation] In the present invention, since the body portion has a relatively large wall thickness, the collapse phenomenon in the body portion can be avoided. Moreover, since the base portion has a small wall thickness, the overall spring constant can be reduced. The desired anti-vibration effect can be improved.

り小さくしたところにある。FIG. 1 shows an embodiment of the present invention. This cushion member 10 has basically the same structure as the cushion member shown in FIG. The feature of the present invention in such a cushion member 10 is that the wall thickness t 1 of the body portion 18 is relatively large and the wall thickness t 2 of the annular base portion 20 is smaller than that.

ぞれの固有振動数を測定し、防振効果とつぶれ現象の有
無を評価した。その結果を表1に示す。One cushion member (thickness of the body portion is larger than that of the base portion) according to an embodiment of the present invention is made, while on the other hand, a comparative example (the body portion and the base portion have the same thickness or the body portion is formed). (Those with a smaller wall thickness) were manufactured, and the natural frequency of each was measured to evaluate the anti-vibration effect and the presence or absence of the collapse phenomenon. The results are shown in Table 1.

すなわち、基部の肉厚が小さいために防振効果はよく、
それにもかかわらず、胴部の肉厚が3.5mmと大きい
ために胴部におけるつぶれ現象も発生しなかったと思わ
れる。[Table 1] As shown in Table 1, in Example 1, the body wall thickness t 1
Is 3.5 mm and the wall thickness t 2 of the base is smaller than 2.5
mm, the natural frequency is 11.5 Hz,
The anti-vibration effect was good, and the crushing phenomenon did not occur.
In other words, the vibration damping effect is good because the thickness of the base is small,
Nonetheless, it is considered that the crush phenomenon in the body did not occur because the thickness of the body was as large as 3.5 mm.

大きく、防振効果は悪い。On the other hand, in Comparative Example 1, the thickness of both the body and the base is 3.5 mm, which is the same as the thickness of the body in Example 1, but in this case, the body is Since the thickness of No. 1 was sufficiently thick as in the case of the embodiment, the crushing phenomenon did not occur, but the thickness of the base portion was larger than that of the embodiment, and the vibration damping effect was poor.
【0012】比較例2においては、胴部、基部ともにそ

現象は若干発生した。In Comparative Example 2, both the body and the base have a thickness of 3.0 mm. The anti-vibration effect was good, but some crushing phenomenon occurred.

現象が発生した。Further, in Comparative Example 3, both the body portion and the base portion had a thickness of 2.5 mm, which is the same as the thickness of the base portion in the embodiment. As described above, since the entire thickness is the same as the thickness of the base portion in the example and is relatively small, the natural frequency is very small and the vibration damping effect is very good. However, the crushing phenomenon occurred because the whole wall thickness was relatively thin.

発生しなかった。In Comparative Example 4, the thickness of the body was the same as that of the example, but the thickness of the base was larger than that of the body. Therefore, although the rigidity of the cushion member as a whole was extremely high and the vibration damping effect was poor, the crushing phenomenon did not occur.

らかである。As described above, in order to prevent the occurrence of the crushing phenomenon, the thickness t 1 of the body is increased (Comparative Example 1,
4) The rigidity of the entire cushion member is increased, the spring constant is increased, the natural frequency is increased, and the vibration damping effect is poor. On the other hand, in the case where it is attempted to reduce the thickness of the entire cushion member to improve the vibration damping effect (Comparative Example 3), the rigidity is poor and the crushing phenomenon occurs. In the case where the entire thickness is in the middle (Comparative Example 2), the spring constant of the cushion member as a whole is relatively small and the vibration damping effect is good, but a slight crushing phenomenon occurs. Therefore, as in the first embodiment of the present invention, it is clear that by reducing only the wall thickness t 1 of the body, it is possible to increase the rigidity of the body and prevent deterioration of the vibration isolation effect.
