Summary:To generally evenly distribute load forces between inner and outer shrouds during turbine operation.SOLUTION: A turbine component provides an inner shroud (22) shielding an outer shroud (14) from a gas path within a turbine (10) during operation of the turbine (10), and the inner shroud (22) includes opposed arcuate portions (26, 28) extending around a corresponding extending portion (16, 18) of the outer shroud (14) and in direct contact with the corresponding extending portion (16, 18) of the outer shroud (14). The component provides a load path forming region (34) at least partially extending between facing surfaces of each arcuate portion (26, 28) and corresponding extending portion (16, 18). During operation of the turbine (10), load path forming regions (34) extend into direct contact between at least a portion of the facing surfaces of each arcuate portion (26, 28) and corresponding extending portion (16, 18), resulting in formation of an even loading arrangement (36) in the load path forming regions (34).SELECTED DRAWING: Figure 1 【課題】タービンの運転中に内側シュラウドと外側シュラウドとの間で荷重力がおおむね均等に分配さする。【解決手段】タービンコンポーネントは、タービン（１０）の動作時にタービン（１０）内のガス経路から外側シュラウド（１４）を遮へいする内側シュラウド（２２）を提供し、内側シュラウド（２２）は、外側シュラウド（１４）の対応する延長部分（１６、１８）の周囲に延び、外側シュラウド（１４）の対応する延長部分（１６、１８）に直接接触する反対向きの弧状部分（２６、２８）を含む。このコンポーネントは、各々の弧状部分（２６、２８）および対応する延長部分（１６、１８）の向かい合う表面の間を少なくとも部分的に延びる荷重経路形成領域（３４）を提供する。タービン（１０）の動作時に、荷重経路形成領域（３４）は、各々の弧状部分（２６、２８）および対応する延長部分（１６、１８）の向かい合う表面の少なくとも一部分の間の直接接触へと延び、荷重経路形成領域（３４）に均等な荷重配置（３６）の形成をもたらす。【選択図】図１
