PURPOSE:To facilitate the work of assembly, disassembly, or others by removing the necessity of the exchange of a center housing itself even if the sliding part of the center housing is worn off. CONSTITUTION:An intermediate ring 15 is provided between a center housing 4 and a floating bush 3, and positioned by a snap ring 17. Lubricating oil supplied from an oil supply hole 13 is sent to the floating bush 3 via an oil supply hole 16. Even if the sliding face of the intermediate ring 15 is worn off, a captioned device can be reused only by exchanging the intermediate ring 15. Meanwhile, when the material of the intermediate ring 15 is selected to be resistive against heat and abrasion only on the side of a turbine, the amounts of wear and tear of left and right intermediate rings 15 can be equalized. |
