PURPOSE:To prevent oil calking, by mounting a driving mechanism, which can freely perform the motoring of an engine after it is stopped, to be engaged with a rotary shaft, in case of the gas turbine engine for an auxiliary power source. CONSTITUTION:A driving mechanism 7, which can perform driving rotation, is mounted to be engaged with a rotary shaft 10 of a small gas turbine engine 1 for an auxiliary power source. When the engine 1 is stopped, the driving mechanism 7 is actuated by utilizing a machine unit electric power supply or a hydraulic pressure source of a main engine when the rotary shaft 10 slows to the speed in which it can be again rotated. In this way, oil calking can be prevented because a bearing part is cooled by performing the motoring action for a fixed time.
