However, in the case of the above prior art, light objects such as lighting fixtures can be mounted on the ceiling frame, but the strength is insufficient for suspending partitions, hanging walls, and particularly heavy objects such as wafer transfer devices. Met. Therefore, in order to suspend the heavy object as described above, it is necessary to directly suspend the heavy object with the suspension bolts suspending the ceiling frame, and for that purpose, the suspension bolts are protruded downward through the ceiling frame. There is a need. However, in this case, if the sealing by the caulking material is not completely performed, there is a possibility that dirty air on the upstream side of the air filter may leak to the clean air side on the downstream side of the air filter. It is virtually impossible to do so. Further, the through holes also reduce the strength of the ceiling frame structure.
