Abstract
A gas turbine comprises a shroud integral type moving blade and a split ring. The moving blade includes a shroud provided from a leading edge of a tip of a moving blade to a trailing edge and whose outer side surface is provided with a seal fin. A radius of a tip end of the seal fin is substantially equal to a radius of a shroud trailing edge end. The split ring has a structure in which a radius of its inner peripheral surface is slightly larger than a radius of the seal fin tip end and the radius of the shroud trailing edge end.
