Abstract PROBLEM TO BE SOLVED: To provide a turbine rotor blade assembly capable of easily assembling a turbine rotor blade at a desired inclination angle.SOLUTION: In a turbine rotor blade assembly 1 of this invention, each turbine rotor blade 10 includes: a platform 11 having a blade room 12 implanted into a blade groove 31 provided on an outer peripheral surface of a turbine disc 30; a profile 13 erecting from the platform 11; and a shroud 14 provided at a tip of the profile 13. The turbine rotor blade assembly 1 is configured such that in assembly, a tip being a specific portion of the platform 11 preferentially contacts with the outer peripheral surface 33 of the turbine disc 30.SELECTED DRAWING: Figure 5 【課題】所望する傾き角でタービン動翼を組み立てるのが容易なタービン動翼組立体を提供すること。【解決手段】本発明のタービン動翼組立体１は、それぞれのタービン動翼１０は、タービンディスクの３０外周面に設けられた翼溝３１に植え込まれる翼根１２を有するプラットフォーム１１と、プラットフォーム１１から立ち上がるプロファイル１３と、プロファイル１３の先端に設けられるシュラウド１４と、を備える。本発明のタービン動翼組立体１は、組み立て時において、プラットフォーム１１の特定の部位である先端が、タービンディスク３０の外周面３３に優先的に接触することを特徴とする。【選択図】図５
