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 hollow space consisting of a main damping portion and a base portion on the inside of the damper, and thereby increasing the flexibility of the damper. CONSTITUTION:A bolt 2 is fixed to a base plate 1, and a disk-like seat 3 formed with a projection 3a on its upper surface is fitted around the bolt 2. Further, a cylindrical damper 4 formed with a hollow space 4a on the inside thereof is fitted to the projection 3a, and a compressor supporting leg 5 is supported at the top of the damper 4. The damper 4 is made of a soft, elastic material such as rubber and formed therein with a through-hole 4b having an inner diameter phiA almost equal to the outer diameter of the bolt 2 that is located at the upper portion of the damper 4 and a large-diameter hollow space 4a hving an inner diameter phiB that is extended from a position DELTAH higher than the height H of the bolt 2 downward to the bottom with the inner diameter phiB unchanged. |
