PURPOSE:To prevent vibration of a compressor from being transmitted by a method wherein there is provided a dampening member between a bottom member on which a main body is mounted and the main body. CONSTITUTION:Compression coil springs 39 and 40 acting as dampening members while being inserted into supporting shafts 35 and 36 are inserted into a space ranging from a bottom plate member 30 to a bottom plate 4 of a main body. The main body 1 is resiliently supported by the springs 39 and 40 and fixed to the bottom plate member 30. Vibration energy transmitted to the bottom plate 4 of the main body is transmitted to the bottom plate member 30 through supporting shafts 35 and 36 as well as springs 39 and 40. At this time, the main body 1 is freely vibrated in respect to the bottom plate member 30 while being resiliently supported by the springs 39 and 40. Due to this fact, vibration energy is mainly consumed for movements of springs 39 and 40 and component of the vibration energy transmitted to a floor surface becomes substantially zero. With such an arrangement as above, it is possible to avoid vibration caused under an operation of a compressor 14 from being transmitted to the floor surface and further to avoid occurrence of noise. |
