Claims

[Scope of utility model registration request]

In a gas turbine combustor that is built into an outer cylinder and supplies fuel and air into an inner cylinder equipped with air holes on the outer periphery, the fuel and air are combusted and sent to a turbine. A gas turbine combustor, characterized in that a reinforcing member is joined thereto, the reinforcing member having a thermal expansion coefficient smaller than that of the inner cylinder and having holes that match air holes in the inner cylinder.
