The fuel nozzle assembly includes a fuel nozzle, a head end plate to which the fuel nozzle is fixedly fastened, and a nozzle casing to which the head end plate is fixed. The fuel nozzle includes an injection cylinder having a nozzle flange fixed to the head end plate, and a nozzle shroud surrounding the injection cylinder and forming a passage between its inner wall and the injection cylinder. The injection cylinder is fastened to the head end plate by a plurality of fixing bolts arranged in a circumferential direction of the nozzle flange. Each of the fixing bolts is fitted to a pressure plate, which extends in the circumferential direction of the nozzle flange and is pressed against a flat surface thereof, to fasten the injection cylinder to the head end plate.
