Abstract: A turbocharger has a center housing (1) and a thin-walled exhaust housing (13). Both housings are connected to each other at cylindrical end portions (28, 27) thereof by use of a floating flange ring (16) having a clamping surface (26b) which upon applying an axial load exerts at least an axial force component for urging the cylindrical end portion (28) of the thin-walled housing (13) against the cylindrical end portion (27) of the center housing (1). The floating flange ring is connected to counter parts by screws, which counterparts are pressed against a flange portion of the center housing so as to clamp to walled housing by means of the floating flange ring.
