A gas turbine includes downstream side members that face a passage and have guide faces arranged in the passage side as it goes toward the upstream side. In a cross section including an axis center of a rotor shaft extending in a flow direction of a gas main stream, extension sections of the guide faces continuing to the upstream end portion of the guide faces are arranged downstream from the cavity inner wall portion of the upstream side member facing the cavities.

Gas turbine

To provide a bearing support structure and a gas turbine that prevent damage of device induced by a rotor shaft when the rotor shaft is unbalanced, the bearing support structure and the gas turbine includes: a casing () formed in a cylindrical shape; a bearing unit () formed in a cylindrical shape and housed in the casing (); a rotation shaft () rotatably supported by the bearing unit (); and a reaction-force decreasing unit () that connects the casing and the bearing unit, and is configured to decrease a radial reaction force on the bearing unit side.
