The doors 14 and 15 are changed in position from a closed position in which the doors are brought into contact with each other and to an open position in which the doors are mutually separated. The flanges 12 and 13 are circularly formed. The doors 14 and 15 are composed of elastic disks. The doors 14 and 15 are bent so that their tips are mutually pushed in a closed position.
