Abstract

A turbine rotor 10 in an embodiment is configured by joining a rotor component member 40 and a rotor component member 50 together by bolt fastening with an abutting end surface 43 of the rotor component member 40 and an abutting end surface 54 of the rotor component member 50 abutting on each other. The turbine rotor 10 includes: a cylindrical recessed portion 64 that is formed at the abutting end surface 43 and is recessed in an axial direction; an axial passage 62 bored from a bottom surface 64a of the cylindrical recessed portion 64 in the axial direction; an introduction passage 61 introducing the cooling medium into the axial passage 62; a discharge passage 63 discharging the cooling medium from the axial passage 62; and a sealing member 65 that is arranged in the cylindrical recessed portion 64 and seals one end of the axial passage 62.
