としたことである。The purpose of the present invention is to focus on the above points, and in assembly and adjustment, it is possible to easily adjust the gap at the tip of the turbine rotor blade with a single component, and also to release the rotor shaft, which is the most difficult part in releasing and restoring the turbocharger. The purpose of the present invention is to provide a structure of a supercharger that makes it easy to inspect and maintain the inside of a gas casing that is fixed in place. Instead of a structure in which the three parts were integrated by sandwiching the outlet guide cylinder, the gas outlet guide cylinder can now be attached and removed independently from the other three parts.

1 is a rotor shaft and a rotor disk.
排気ガスの流れは矢印で示されるが、この流れは第１図
の従来例のものの流れとは逆であり、そのためガス入口
及びガス出口ケーシング等の位置が第１図のものと異な
っている。The flow of exhaust gas is indicated by arrows, but this flow is opposite to that of the conventional example of FIG. 1, and therefore the positions of the gas inlet and gas outlet casings, etc. are different from that of FIG.
ガス入口ケーシングは内外二律に分割されたガス入口ケ
ーシング内室３及び同外室４で構成され。The gas inlet casing is composed of an inner chamber 3 and an outer chamber 4, which are divided into an inner and an outer chamber.
それぞれロータ、即ちロータ軸及びロータディスク７に
対向して配設されている。They are arranged opposite to the rotor, that is, the rotor shaft and the rotor disk 7, respectively.
タービンノズル５はガス入口ケーシング内室３に固定さ
れている３ガス出ロケーシング１はロータ側に配設され
、ガス入口ケーシング外室４に結合されている。The turbine nozzle 5 is fixed to the gas inlet casing inner chamber 3. The gas outlet casing 1 is arranged on the rotor side and is connected to the gas inlet casing outer chamber 4.
