PURPOSE:To prevent the contact between a frame and an operation room by a method in which projections are each provided to the upside and downside of the frame, and the projections are fitted into recessions provided in a buffer to integrally join the frame with the buffer. CONSTITUTION:Projected portions 1A and 1B having projections 1Aa, 1Ab, 1Ba and 1Bb which are inclined at 55 deg. to a frame 1 are provided to the upside and downside of the frame 1. The projections 1Aa, 1Ab, 1Ba and 1Bb are fitted into recessions 5Aa, 5Bb, 5Ca and 5Da provided in vibration-insulating rubbers 5A, 5B, 5C and 5C. Covers 6a and 6b are provided on the vibration-insulating rubbers 5A, 5B, 5C and 5D, and an operation room floor 7 is set on the cover 6a. The covers 6a and 6b and the floor 7, and the frame 1 are integrated with bolts 3 and nuts 4. The transmission of vibration from the frame 1 to the operation room can thus be prevented. |
