In an axial flow gas turbine efficient cooling and a long life-time can be achieved by providing the outer blade platforms () with a plurality of outer teeth (-) running parallel to each other in the circumferential direction and being arranged one after the other in the direction of the hot gas flow. The teeth (-) are divided into first and second teeth (-), the second teeth (-) being located downstream of the first teeth (), the first teeth () are opposite to a downstream projection () of the adjacent vanes () of the turbine stage (TS), and the second teeth (-) are opposite to the respective stator heat shields ().
