Bolt holesare formed in a joint partof a turbine housing, with flanged boltsscrewed in the bolt holes. A flange partof a bearing housingis sandwiched between bearing surfacesof the flanged boltsand an inner end faceof the joint part. A sealing ringis interposed in an annular space s. Before the flanged boltsare fastened, there is formed a height difference G equivalent to a compression allowance h for the sealing ring, between an outer end faceof the joint partand a bolt receiving surfaceof the flange part. The flanged boltsare screwed into the bolt holesuntil the bearing surfacesmake tight contact with the outer end faceso as to resiliently deform the sealing ring
