Abstract:
1. A turbine rotor blade assembly comprising: an airfoil; a shroud provided at a tip of the airfoil; a blade root projecting toward a radially internal circumferential side of a turbine rotor and fitted to a root attachment provided on an outer circumferential portion of the turbine rotor; a platform provided between the airfoil and the blade root; a pin provided between the blade root and the root attachment; a bore formed between respective surfaces of the platforms facing each other and included in the respective adjacent rotor blades; and a bar-like member provided in the bore with a clearance formed between the bore and the bar-like member; wherein a clearance between the bore and the bar-like member during assembly is made smaller than a difference of displacement in the radial direction between respective bores of the platform surfaces adjacent to each other, during rotation of a turbine.
