<P>PROBLEM TO BE SOLVED: To improve airtightness and durability of an exhaust turbocharger so as to prevent a component from malfunctioning later due to a thermal load, and to correct thermal expansion depending on heat by assembling the exhaust turbocharger. <P>SOLUTION: A turbine housing 1 of an exhaust turbocharger 2 includes an outer housing 4 and an inner housing 3 such that the inner housing 3 is coupled to a tubular connection tube 5 for fitting a bearing housing of the turbocharger. The inner housing 3 and the connection tube 5 are engaged with each other. The inner housing 3 grips the connection tube 5 from inside, and has an edge curved radially outward along a flange collar 7 of the connection tube 5, and a press ring 11 for additional position fixation is arranged adjacent to an edge-curved end 9. A brazing coupling part is arranged between the press ring 11 and the edge-curved end 9. <P>COPYRIGHT: (C)2013,JPO&INPIT |
