付構造。 A turbine nozzle integrally configured with a nozzle blade, an outer peripheral ring located on the outer periphery of the nozzle blade, and an inner peripheral ring located on the inner peripheral side of the nozzle blade is fitted into a bearing housing that supports a turbine rotor via a bearing. In a gas turbine installed through a joint, the inner peripheral ring of the turbine nozzle is provided with a tapered flange whose wall thickness becomes smaller toward the inside in the radial direction, and the tapered flange is a member fastened to the bearing housing. A nozzle mounting structure for a gas turbine, characterized in that the same taper as the tapered flange is provided between the flange and the bearing housing.
