A turbine rotor for a gas turbine includes first and second wheels each having turbine blades fixed to a peripheral portion thereof, and a spacer arranged so as to be sandwiched between the first and second wheels. A partitioning member is provided between the spacer and at least one of the first and second wheels. Coolant paths in which coolant for cooling the turbine blades flows, are provided inside the turbine blades. A cavity formed by the partitioning member and the spacer is provided in a recovery course through which the coolant passed through the coolant paths is exhausted from the turbine blades.

1. A turbine rotor comprising:a plurality of turbine blades each having a coolant path formed inside and permitting coolant to flow therein; a plurality of wheels having said plurality of turbine blades arranged annularly in peripheral portions thereof and forming said turbine rotor; annular members each arranged between adjacent wheels of said plurality of wheels; heat-resistant members provided on side surfaces of said wheels positioned at side surfaces of said annular members; and wherein said coolant paths are formed so as to be positioned between said annular members and said heat resistant members and the coolant heated through heat-exchange with said turbine blades and flowing down through said coolant paths, faces said annular members.
