PROBLEM TO BE SOLVED: To provide a seal attached to a member on one side among two opening and closing members to seal a section between two members when two members are closed and capable of preventing occurrence of leaving and rupture of seal rubber by opening two members, providing stable seal performance, and mounting a seal rubber simply even when constituting a large-sized seal. SOLUTION: The seal rubber 3 is mounted in a first peripheral channel part 2 provided on a main face 1A on one side of a main body fitting 1 like substantially flat plate, and a second peripheral channel part 4 and a plurality of communicating holes 5 for communicating between the second peripheral channel part 4 and the first peripheral channel part 2 are provided on a main face 1B on the other side of the main body fitting 1. A locking rubber 6 arranged in the second peripheral channel part 4, the seal rubber 3, and a bridge rubber 7 arranged in the communicating hole 5 are mutually integrated. The first peripheral channel part 2 is a dovetail groove, and the second peripheral channel part 4 has such shape that an inner side face whose channel width is sequentially reduced from its channel opening side to a channel bottom face side is inclined. Channel width D4-2 of a channel bottom face is substantially the same as inside diameter D3 of the communicating hole 5. COPYRIGHT: (C)2006,JPO&NCIPI
