Abstract

A turbine exhaust structure is provided for a vehicle which includes an exhaust tail pipe having an inner wall defining a screw hole. The turbine exhaust structure includes a turbine exhaust device secured in the inner wall of the exhaust tail pipe, and a bolt co-operating with a nut for securing the turbine exhaust device in the inner wall of the exhaust tail pipe through the screw hole. The turbine exhaust device includes a housing secured in the inner wall of the exhaust tail pipe, a wheel disk secured in the housing, a plurality of catch pieces mounted in the wheel disk, an axle base secured in a central portion of the wheel disk, an axle rod rotatably mounted in the axle base of the wheel disk and having a first end provided with a first vane wheel and a second end provided with a second vane wheel, and two bearings mounted between the axle base and the axle rod.

Claims
