Abstract

Die Erfindung betrifft eine Leitschaufel (1) für eine Gasturbine mit einer Vorderkante (12) und einer Hinterkante (8) und einer zumindest zwischen der Vorderkante und der Hinterkante verlaufenden Deckplatte (2). Die Deckplatte weist im Wesentlichen sich radial und in Längsrichtung der Gasturbine erstreckende erste und zweite Seitenwände auf (5, 6). Die erste Seitenwand (5) zumindest im Bereich der Hinterkante ist mit einer in Längsrichtung der Deckplatte verlaufenden Nut (7) zur Aufnahme einer Dichtungsplatte versehen, wobei die erste Seitenwand der Deckplatte im Bereich der Hinterkante eine sich von der Nut aus erstreckende Aussparung (10) aufweist.
