Using a clean box 30 which includes a box body 31 having an annular groove 33 for suction surrounding a side aperture 32 and an intake/exhaust port 34 in communication therewith, a side lid 35 for closing the aperture 32 while being sucked by a pressure difference between inside and outside a space
Using a clean box 30 which includes a box body 31 having an annular groove 33 for suction surrounding a side aperture 32 and an intake/exhaust port 34 in communication therewith, a side lid 35 for closing the aperture 32 while being sucked by a pressure difference between inside and outside a space S for suction formed by the annular groove 33 for suction, and an additional lid 36 for closing the intake/exhaust port 34 by a pressure difference between inside and outside thereof, the clean box 30 is connected to a gate aperture 42 of a clean room 40, a vacuum changer 50 evacuates a hermetically closed space outside the box body including the additional lid 36 to cancel the pressure difference between inside and outside of the additional lid 36 and opens the intake/exhaust port 34 to turn the space S for suction into the atmospheric pressure, the side lid 35 is drawn into the clean room 40 to establish communication between the clean box and the inside of the clean room, and objects to be transferred are then transferred between the clean box and the clean room.
