Abstract
In a cascade device for a gas turbine, cooling air which has passed through a trailing air cooling chamber of each stationary blade is discharged from a tip of the stationary blade toward a side surface of a base of a moving blade disposed adjacent to the stationary blade. With this arrangement, the cooling of the stationary blade as well as the sealing of a cascade portion is effected satisfactorily with a smaller amount of the air.
