In a gas turbine engine having a diffuser provided downstream of the power section and composed of inner and outer diffuser wall members forming therebetween a diffuser chamber which is open into an exhaust gas collector chamber, the outer diffuser wall member is provided with at least one flow guide member which extends on the generally frustoconical outer peripheral surface of the outer diffuser wall member and which is curved arcuately or circularly about the common center axis of the inner and outer diffuser wall members for thereby suppressing formation of vortices in the flow of the combustion gases being exhausted through the collector chamber.
