PURPOSE:To usually perform the automatic adjustment of a base level by providing the subject leveling device composed of a horizontal adjustment lever for sensing the vibration or oscillation of a body to be horizontally adjusted and a valve part. CONSTITUTION:An elastic body A is composed of an air spring part 3 arranged between an upper base 1 and lower base 2. A leveling device B has a horizontal adjustment lever 4 for executing a horizontal adjustment function and vibration proofing function of the upper base 1 and valve parts 5, 6, 7. The valve part 5 has an air supply function to the elastic body A, the valve part 6 has an air exhaust function from the elastic body A and the valve part has an air supply or air exhaust function to a vibration isolator. Thus, it is possible to usually perform the automatic adjustment of the base level so as to automatically prevent the vibration of the base. |
