In a gas turbine, in which a compressor and a turbine are connected by means of a distant piece, the distant piece and a turbine first-stage disk 1 are connected by means of a joint portion. On the distant piece is formed a projection portion, and a spacer is held by means of a spigot portion. Thin portion is formed on an outer diameter side of the spacer, and is in contact with a fin of a turbine disk through a seal member. The turbine disk, the distant piece and the spacer define a cavity.
