The guide vane unit 2 supports the shafts 22 of guide vanes 1 so as to rotatably hold them between a bearing ring 14, which is divided by opposite faces, and a press ring 15. The shaft 22 of one of the guide vanes 1 is driven by a rotating shaft which passes a through-hole 28 provided in the housing 3. The housing assembling structure includes a radial fixing means 37 for restraining radial movement of the guide vane unit 2 fitted to the stepped portion 10 of the housing 3, and an axial fixing means 40 restraining axial movement of the guide vane unit 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
