In a compressor (11) of a turbocharger (1), a compressor wheel (14) is provided in a housing (12) to be capable of rotating. When the wheel (14) rotates, air suctioned through an inlet of the housing (12) is compressed and then discharged through an outlet of the housing (12). Further, an abradable seal layer (16) formed on an inner surface of the housing (12) is abraded by a vane (13) of the rotating wheel (14) such that a tip clearance between the vane (13) and a part of the inner surface of the housing (12) that opposes the vane (13) is adjusted. A corner portion (13a) of the vane (13) on the outlet side of the housing (12) is shaped to move gradually further away from a shroud curve (Lc) of the seal layer (16) toward an end portion of the vane (13) on the outlet side of the housing (12).
