PROBLEM TO BE SOLVED: To provide an internal tank mounting structure where space saving is ensured to realize compact housing for a combustor, mounting/replacing work is significantly facilitated, and the number of parts is reduced. SOLUTION: A connection joint 7 and a support bracket 8 are fixed integrally to an internal tank 2, while an external joint 5 connected with external piping is fixed to a reinforcement bracket 9 fixed to a housing bottom plate 3, through which a sight cover 4 is made to penetrate. The internal tank is moved from the left to the right in Fig. to pressure-insert the connection joint into a reception hole 56 of an external joint. In this connection state, a holding piece 84 on the left and right sides of the support bracket holds a front end of the slit hole 33 of the bottom plate for preventing a vertical displacement, and a rear side support leg 82 is brought into a contact with a coupling piece 31 and coupled with a screw 11. By inserting the holding piece into the slit hole a displacement in the direction perpendicular to the figure is arrested, whereby positioning of the engagement of the connection joint with the external joint is ensured, and the movement of the internal tank from the left to the right is guided.
