PURPOSE:To improve the vibration damping properties of an apparatus for supporting a compressor by fitting a damper to a bolt fixed to a base plate, by forming a large-diameter space in the damper at the middle portion of a through-hole formed in the damper, and thereby making deformation of the damper flexible. CONSTITUTION:A bolt 2 is fixed to a base plate 1, and a damper 3 made of an elastic material such as rubber is fitted to the bolt 2. A support leg 4 of a compressor is supported at the top of the damper 3. As for the internal configuration of the damper 3, a through-hole 5 is formed at the central portion of the damper 3 in the manner that its inner diameter phiA at the upper portion and the inner diameter phiC at the lower portion are about 1-1.5 times greater than the outer diameter phiB of the bolt 2, and a large-diameter space 5a having a diameter D more than two times greater than the outer diameter phiB of the bolt 2 is formed to extend from a portion DELTAH higher than the height H of the bolt 2 downward to the position where the bolt 2 is projected. Further, a conical space 5b, the diameter of which is reduced gradually toward the bottom, is formed downwardly of the large-diameter space 5a on the side of the bolt 2. |
