A gas turbine having a structure for collecting a refrigerant after cooling the moving blades, has a plurality of wheels having a plurality of moving blades including cooling paths in the outer periphery and a plurality of spacer members alternately arranged on the rotating axis. A plurality of flow paths through which a refrigerant flows after cooling the moving blades are provided in the spacer members. First flow paths interconnect the moving blades arranged on the wheels on the upstream side of gas flow to the downstream side of gas flow of the spacer members, and second flow paths interconnect the moving blades arranged on the wheels on the downstream side of gas flow to the upstream side of gas flow of the spacer members. The flow paths may be provided with bent parts in the neighborhood of the center of the space members in the axial direction or may be in a linear shape.

1. A gas turbine comprising a turbine rotor including a plurality of moving blades having cooling paths through which a refrigerant flows inside, a plurality of wheels having said moving blades mounted in the outer periphery thereof, and at least a spacer member installed between said wheels, whereinsaid spacer member has a plurality of flow paths through which a refrigerant flows after cooling said moving blades, said plurality of flow paths have first flow paths interconnecting to said cooling paths in said moving blades on a first wheel adjacent said spacer member and interconnecting to a first space formed on a side wall surface with which a second wheel adjacent said spacer member and said spacer member are in contact, and second flow paths interconnecting to said cooling paths in said moving blades on said second wheel and interconnecting to a second space formed on a side wall surface with which said first wheel and said spacer member are in contact.
