Abstract
A turbine rotor blade assembly in which values A, CF, T, and L are set to satisfy the following expression in two-dimensional coordinates, 1.2×10≤(A×CF)/(T×L)≤17×10, where (A×CF)/(T×L) is an expression (1), A is an arm length [mm] of each of turbine rotor blades, CF is centrifugal force [kgf] occurring on each of the turbine rotor blades, T is a thickness [mm] of each of shrouds, and L is a lap amount [mm] of the shrouds adjacent to each other.
