Abstract (en)
[origin: EP2151545A2] Disclosed is a turbine rotor blade 40a, 40b that is highly manufacturable and capable of reducing the stress caused by centrifugal force. The turbine rotor blade 40a includes: a vane portion 3 having a blade leading edge 21 which is positioned upstream in the distribution direction of working fluid, and a blade trailing edge 22 which is positioned downstream of the blade leading edge 21; and a blade base 5 portion which is extended unidirectionally on a base side of the vane portion 3 and engaged with a blade groove 6 formed in the outer circumference of a turbine rotor 8. The turbine rotor 8 circumferential position of the end of the blade base portion 5 on the side toward the blade leading edge 21 is different from the turbine rotor 8 circumferential position of the end of the blade base portion 5 on the side toward the blade trailing edge 22.
