摘要： In a turbine rotor in which a rotor material has lower tensile strength than a blade material and the difference in tensile strength between both the materials is large, a strength margin on the blade side is properly distributed to a strength margin on the rotor side with the aim of reducing shear stress in a rotor hook, increasing stiffness of the rotor hook, and reducing peak stress in a rotor neck, to thereby provide a steam turbine rotor and an inverted fir-tree turbine blade in which stress balance is made more appropriate depending on a material strength ratio of the blade material to the rotor material. In the turbine rotor, a rotor radial-direction hook length (Hri) of an i-th rotor hook counting from the outermost circumference of the rotor and a blade radial-direction hook length (Hbi) of an i-th blade hook counting from the outermost circumference of the blade are set to satisfy the relationship of (Hri>Hbi). In the turbine blade, a rotor circumference-direction neck width (Wri) of an i-th rotor neck counting from the outermost circumference of the rotor and a blade circumference-direction neck width (Wbi) of an i-th blade neck counting from the innermost circumference of the blade are set to satisfy the relationship of (Wri>Wbi).
