    摘要: A gas turbine including a joint structure is disclosed. According to the joint structure, a ceramic shaft is received in a bore formed in an end portion of a metallic shaft. Brazing filler metal made of Ag-Cu alloy is distributed between the closely fitted surfaces of the ceramic shaft and bore wall, and it extends axially toward the open end of the bore up to a predetermined plane where a ring seal groove formed on the end portion of the metallic shaft lies. The open end of the bore is closed to prevent entrance of exhaust gas into the bore.
