PROBLEM TO BE SOLVED: To provide a regenerative cycle gas turbine device 1 improved in durability and saved in space for installation. SOLUTION: An outer box 10 includes: a compressor 2; a turbine 3; and a regenerator 7 having an air flow passage A and an exhaust flow passage E and previously heating the compressed air with the combustion gas, and a second outer box 20 includes a combustor 8. The outer boxes include an exhaust pipe 14 for leading the combustion gas in one way from the turbine to discharge outside of the outer box through an exhaust opening 15. The exhaust flow passage of the regenerator is directly connected to a middle part of the exhaust pipe, and an inlet of the air flow passage of the regenerator is opened inside of the outer box, and an outlet is communicated with the second outer box. Since the regenerator is directly connected to the middle part of the exhaust pipe inside of the outer box, piping for connection outside of the outer box is unnecessary, a space can be saved and costs can be reduced, heat efficiency is improved, tensile stress by the inner pressure of the air flow passage of the regenerator is offset to improve durability.
