Claims

[Scope of utility model registration request]

In the upstream support part of a gas turbine combustor liner having a cylindrical shape, the support part has a plurality of pipe-shaped support members arranged at equal intervals on the circumference of the liner so as to face the center of the liner. The liner is inserted in the downstream direction into a plurality of U-shaped support members provided on the inner wall of a cylindrical outer cylinder arranged concentrically with the liner so as to be paired with the liner support part. A support structure for a combustor, characterized in that the liner is fixed within the outer cylinder by inserting into the pipe-shaped support member a fixing member that is screwed into the center of the liner from the outer surface of the cylinder.
