Abstract: The present invention relates to a micro gas turbine with a compact structure. More specifically, a sub journal bearing is placed between a thrust collar and a wheel of a compressor which means the bearing is placed around the thrust bearing at a compressor so that the whole length and weight of a rotator are reduced to form the compact structure. A pair of main journal bearings separated from each other at a certain distance is placed between a hollow shaft and a sleeve. The main journal bearings fully support a shaft between the compressor and turbine wherein dynamic pressure is heavily applied caused by rotation in order to maximize safety. For the purpose, the present invention comprises a turbine wheel; a tie shaft which one end part is connected to the turbine wheel; a compressor wheel which is separated from the turbine wheel to be inserted into the tie shaft; a thrust rotor separated from the compressor wheel to be fixed to the end part of the tie shaft; the thrust collar placed on a part of the outer surface of the thrust rotor; and the sub journal bearing equipped between the thrust collar and the compressor wheel.
