Abstract: PROBLEM TO BE SOLVED: To provide a fuel nozzle guide which can improve a cooling flow on a bulkhead heat shield without increasing the level of the cooling flow of a combustion machine in a gas turbine engine. SOLUTION: A nozzle guide 50 comprises a circular bushing 52 having a dimension enough to insert a nozzle 46 and one end part of the circular bushing 52 is linked to a nozzle guide retainer 56 while the other end part thereof forms a flange part 54 extending radially. The flange part 54 has a periphery part as peripheral portion away from a body part as body close to a link part of the circular bushing 52. The periphery part is extended in substance parallel with a combustion chamber bulkhead heat shield 58 while a rib is formed extending radially on the perimeter of the periphery part of the flange part 54. Each rib has a head end part and a tail end part and the tail end part is shaped into a circular arc. The vortex of a filmy cooling air passing between the end parts is reduced to supplement the bulkhead heat shield 58.
