It exhibits strong durability against vibration and thermal deformation. Further, the partition plate is firmly fixed and positioned in a self-centering manner by the wedge action, regardless of the degree of temperature expansion or dimensional errors of each part.

状溝９に嵌合させることにより、中仕切板６をタ
ービンハウジング１に固定している。 The partition plate 6 is formed in a donut shape to match the inner circumference of the turbine housing 1, and the connecting portion between the two is as follows.
The inner peripheral end of the annular support plate 7 provided on the turbine housing 1 is formed into a tapered part 8, and an annular groove 9 is formed in the outer peripheral end of the partition plate 6, and the tapered part 8 is fitted into the annular groove 9. As a result, the partition plate 6 is fixed to the turbine housing 1.

間に支持板７が挟持される。 Note that the annular support plate 7 is connected to the turbine housing 1.
In order to attach the turbine housing 1 to the turbine housing 1, the turbine housing 1 is divided into two parts along a plane perpendicular to the rotating shaft 3, and the support plate 7 is sandwiched between grooves 10 formed circumferentially along each divided part.
以上したがつて、中仕切板６は環状の支持板７
に形成したテーパ部８が、中仕切板６の環状溝９
に嵌合することにより、しつかりと固定される。 Accordingly, the partition plate 6 is an annular support plate 7.
The tapered portion 8 formed in the annular groove 9 of the partition plate 6
It is firmly fixed by fitting.

食い込んでいき、中仕切板６をしつかりとその位
置に拘束できる。 When high-temperature exhaust gas is introduced into the passages 5a and 5b, the middle partition plate 6 thermally expands, but since the middle partition plate 6 is in contact with the support plate 7 on a tapered surface, the middle partition plate 6 Even if it expands in the diametrical direction, it will dig in due to the wedge action, and the partition plate 6 can be firmly restrained in that position.
この場合、中仕切板６と支持板７はテーパ面で
環状溝９の縁部に線接触しているだけなので、膨
張により過大な熱応力が中仕切板６等に発生する
ことがない。 In this case, since the partition plate 6 and the support plate 7 are only in line contact with the edge of the annular groove 9 on their tapered surfaces, excessive thermal stress is not generated in the partition plate 6 and the like due to expansion.
また、このことは中仕切板６と支持板７の接続
部における直径方向の寸法精度をそれほど高めな
くても、中仕切板６の確実な支持が可能となるこ
とを意味する。 Furthermore, this means that the partition plate 6 can be supported reliably without increasing the dimensional accuracy in the diametrical direction at the connecting portion between the partition plate 6 and the support plate 7.
なお、テーパ部８と環状溝９の内外の位置関係
を逆にしても本考案が成立することは言うまでも
ない。 It goes without saying that the present invention can also be achieved even if the internal and external positional relationship between the tapered portion 8 and the annular groove 9 is reversed.

る。(Effects of the invention) As described above, according to the invention, a tapered part is formed on one of the connection parts between the annular support plate provided on the inner periphery of the turbine housing and the outer periphery of the partition plate, and the tapered part is formed on the other side. An annular groove is formed into which this tapered part is inserted, and the tapered surface of the tapered part and the edge of the annular groove are brought into line contact by fitting them together, so that the diametrical dimension at the connection part between the partition plate and the support plate While it is possible to reliably support the partition plate without increasing precision, even if the partition plate expands due to high-temperature exhaust gas introduced into the turbine housing, the tapered part does not wedge into the annular groove. It securely restrains the partition plate without digging in or generating excessive thermal stress, and exhibits strong durability against vibration and thermal deformation.
