PROBLEM TO BE SOLVED: To provide the seal structure of sliding double doors sealing between pipe end faces and the doors and door mating faces without hindrance. SOLUTION: In the seal structure of the sliding double doors moved in the direction that the doors are crossed over a pipe, the seal structure of the sliding double doors has pipe end-face seal members, which are installed, surrounding the openings of the pipe end faces and to which the internal surfaces of the two doors are slid while being contacted, and door mating-face seal members projected and mounted to the door mating faces of the doors. The door mating- face seal members have side end sections directly brought into contact with the pipe end-face seal members on both sides of the openings and are formed continuously between the side end sections on both sides, the pipe end-face seal members are constituted so that low frictional resin materials are stuck on the surfaces of sections brought into contact with the door mating-face seal members within the open-close ranges of the doors, vibrations between both seal members by friction, the plucking of contacting sections, the generation of cracks and openings by the taking of the door mating-face seal members are removed, and the pipe end faces are sealed surely. |
