PURPOSE:To obtain the high vibration absorbing efficiency in all the directions by installing the upper and lower supporting bodies which move vertically, interposing a ring-shaped rubber tube charged with the air having a prescribed pressure, and by installing the shift regulating plates which contact the inside or outside of the tube, onto each supporting body. CONSTITUTION:A vibrationproof board 12 is installed at the position of each wheel 10 of an air compressor 9, and the compressor 9 is supported onto a floor surface through the vibrationproof board 12. Therefore, even if the compressor 9 operates, and the vibration is transmitted onto the vibrationproof board 12, the compressor 9 is supported between the upper and lower parts of a rubber tube 2 formed into a ring form and the inner and outer wheels. Therefore, the vibration of the compressor 9 which acts in all the directions of the vibrationproof board 12 is absorbed uniformly in reasonable ways by the whole tube 2. Further, the sliding between the tube 2 and the upper supporting body 4, lower supporting body 5, the first and second regulating plates 6 and 7 can be improved by planting wires 3 onto the outer peripheral surface on the sectional surface of the tube 2, and the movement of each member is made smooth, and the vibrationproof effect and the durability of the tube 2 can be improved markedly. |
