PURPOSE:To reduce cost by journaling a capacity varying member of a variable capacity radial turbine to an adaptor and mounting on the turbine housing thereby enabling forming of turbine housing with single member. CONSTITUTION:An adaptor mounting hole 11a is formed in the side wall section of a turbine housing 11 corresponding with start of wind of a scroll path 12 then an adaptor 13 is pressure inserted and fixed. The adaptor 13 is formed with a shroud section 3a near to the turbine rotor 14, while it is formed such that the shaft 15 can be inserted in parallel with the rotary shaft 14a of the turbine rotor 14 and an arched variable capacitor member 16 curved along the scroll path 12 is fixed to the shaft 15. One end of the shaft 15 is inserted into a hole 11b of the housing 11 and supported rotatably while the other end is projected from the adaptor 13 to the outside of housing 11 and coupled to the actuator. |
