An example of a conventional compressor mounting structure will be explained with reference to FIGS. 2 and 3. In the conventional vibration isolating rubber 5 for a compressor, the neck 5c between the load receiving part 5b and the pull-out prevention umbrella 5a was cylindrical. When inserted, the falling-off prevention umbrella 5a was difficult to bend in the opposite direction to the insertion direction, resulting in poor insertion performance. In addition, since the neck 5c is cylindrical, if the installation of the compressor 1 is slightly deviated, the mounting legs 2 of the compressor 1 will push the neck 5c and the inner side 5e of the neck 5c will hit the stud bolt 4, and the vibration of the compressor 1 will be sufficient. The disadvantage is that the power is transmitted from the stud bolt 4 to the base 3 without being attenuated.

When inserting a conventional compressor vibration isolator into the hole in the compressor's mounting leg, the pull-out prevention umbrella does not bend properly and if you push it too hard, the load receiving part will bend, so screw in the compressor vibration isolator. I had to insert it. Furthermore, when we analyzed the transmission of vibration from the compressor, we found that it was transmitted to the stud bolt from the neck between the load receiving part and the pull-out prevention umbrella.
The present invention was conceived as a method for solving these two problems at the same time.

An embodiment of the present invention will be described below with reference to FIGS. 1, 4, and 5. 1 is a compressor, 2 is a mounting leg for the compressor, 3 is a base, 4 is a stud bolt that supports the compressor 1 on the base, and 5 is a vibration isolator for the compressor that damps vibration transmission from the compressor 1 to the base 3. Rubber 6 is a push nut that prevents the vibration isolating rubber 5 from coming off. The fall-off prevention umbrella 5a for the purpose of preventing the attachment leg 2 of the compressor 1 from coming off and buffering between the attachment leg 2 and the push nut 6 is made into a truncated conical shape, and the cylindrical load receiving portion of the vibration isolating rubber 5 for the compressor is provided. The neck 5c between the pull-out prevention umbrella 5a and the pull-out prevention umbrella 5a is made into a truncated conical shape, so that the outer diameter of the upper surface of the pull-out prevention umbrella 5a is d1 , the outer diameter of the lower surface of the pull-out prevention umbrella 5a is d2 , and the upper outer diameter of the neck 5c is d3. , the dimensional relationship between the lower outer diameter d 4 of the neck 5c and the inner diameter d 5 of the mounting hole 2a of the mounting leg 2 of the compressor 1 is d 1 < d 5 < d 2 and d 1 > d 3 , and d 3 <d 4 <d 5 <d 2 . Furthermore, the inside 5d of the vibration isolating rubber 5 for the compressor
is hollow, and the inner side 5e of the neck 5c has a truncated conical shape with the same slope as the outer side.

According to this embodiment, when inserting the compressor vibration isolating rubber 5 into the mounting hole 2a of the mounting leg 2, d 1 <
Since d 5 < d 2 , when the truncated conical inclined surface of the falling-off prevention umbrella 5a comes into contact with the edge of the mounting hole 2a of the mounting leg 2 and is further pressed, d 1 > d 3 . Because of this, the falling-off prevention umbrella 5a is easily bent in the insertion direction, and can easily pass through the attachment hole 2a without deforming other parts too much. Thereby, by simply placing the compressor 1 on the compressor vibration isolating rubber 5, the compressor vibration isolating rubber 5 can be inserted and attached into the mounting hole 2a by the weight of the compressor 1. Furthermore, by setting the dimensional relationship between the height 2 of the neck and the distance 1 between the load receiving part 5b and the outer periphery of the pull-out prevention umbrella 5a to be 1 < 2 , the length of the inclined surface of the pull-out prevention umbrella 5a can be reduced as shown in the figure. Since it can be made larger, it becomes easier to bend the falling-off prevention umbrella 5a in the insertion direction, and the ease of insertion and installation is further improved. Furthermore, even if the installation position of the compressor 1 is shifted from the center position, the dimensional relationship is d 3 < d 4
Since <d 5 <d 2 , the inclined surface of the truncated conical neck 5c and the edge of the mounting hole 2a will slip and try to correct the misalignment, and the lower outer diameter of the neck 5c will be smaller than the outer diameter d 4 . The displacement can be absorbed by the larger inner diameter d5 of the mounting hole 2a. Therefore, even if the mounting position of the compressor 1 deviates from the center position and the neck 5c is pushed by the mounting leg 2, the gap between the inside of the compressor vibration isolating rubber 5 and the stud bolt 4 can be easily maintained. Therefore, transmission of vibration from the mounting leg 2 of the compressor 1 to the stud bolt 4 can be easily and reliably prevented.

According to the present invention, when inserting the vibration isolating rubber for a compressor into the mounting hole of the mounting leg, since d 1 < d 5 < d 2 , the truncated conical inclined surface of the drop-out prevention umbrella is inserted into the mounting hole. When it comes into contact with the edge of the leg's mounting hole, the misalignment between the center of the circle of the truncated conical umbrella and the center of the circle of the mounting hole is corrected, and when it is pressed further.
Since d 1 > d 3 , the pull-out prevention umbrella is easily bent in the opposite direction to the insertion direction, other parts are not deformed much, and the pull-out prevention umbrella can easily pass through the attachment hole. As a result, by simply placing the compressor on the compressor vibration isolating rubber, the compressor vibration isolating rubber can be inserted and attached into the mounting hole by the compressor's own weight.

Furthermore, by setting the dimensional relationship between the height of the neck 2 and the distance 1 between the load receiving part and the outer periphery of the umbrella to prevent it from coming off as 1 < 2 , the length of the sloped surface of the umbrella to prevent it from coming off can be increased, which prevents it from falling off. The ease with which the umbrella can be bent in the direction opposite to the insertion direction is increased, further improving the ease of insertion and installation.

In addition, even if the compressor installation position deviates from the center position, since the dimensional relationship is d 3 < d 4 < d 5 < d 2 , the slope of the truncated conical neck and the mounting hole edge And try to correct the slippage and lower neck outer diameter D4 than the inner diameter of the mounting hole
The larger d5 is, the more the deviation can be absorbed. Therefore, even if the mounting position of the compressor deviates from the center position and the upper part of the neck is pushed by the mounting legs, it is possible to easily maintain the gap between the inside of the vibration isolating rubber for the compressor and the stud bolt. Vibration transmission from the mounting leg of the compressor to the stud bolt can be easily and reliably prevented.
