Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a double-walled conical bearing body capable of blocking up an open clearance between a bearing housing and an exhaust frame structure of a gas turbine. SOLUTION: The double-walled bearing conical body can block up an open- clearance between a bearing housing and an exhaust frame of a gas turbine. The conical bearing body contains a conical front plate 14 provided with an inner diameter and an outer diameter, and a conical rear plate 12 arranged on the conical front plate at intervals in a nest type. A hub 16 is connected to the inner diameters of the front plate and the rear plate. The hub is preferably provided with a hole for regulating the air flow between the front plate and the rear plate. The double-walled conical bearing body forms a cooling circuit to reduce the friction between a third stage turbine wheel and a rotor- rear part shaft of a gas turbine.
