摘要： PURPOSE:To conduct sink-and-float operation safely and positively regardless of the status of the field of execution. CONSTITUTION:A curtain droopingly provided section 2a, to which a curtain 1 is droopingly provided, is installed to an air float 2. A non-curtain droopingly provided section 2b extended from the section 2a only by fixed length is continued to the curtain droopingly provided section 2a. A suction and exhaust section 24 is connected to the end section of the non-curtain droopingly provided section 2b. A reinforcing member 26 preventing the generation of buckling between both the non-curtain droopingly provided section 2b and the curtain droopingly provided section 2a is arranged between both sections 2b and 2a. Since the light-weight non-curtain droopingly provided section 2b is mounted on the suction and exhaust section 24 side, the curtain droopingly-provided section 2a side end section of the air float 2 is sunk first, and the non-curtain section 2b is floated first. Since the reinforcing member 26 for preventing buckling is set up, the generation of buckling between the non-curtain droopingly provided section 2b and the curtain droopingly provided section 2a can be obviated in the supply process of air.
