PROBLEM TO BE SOLVED: To easily remove a liner and a stator from a generator housing to exchange only the liner and the stator during maintenance and inspection, and thereby to reduce a maintenance and inspection cost. SOLUTION: The exhaust turbine supercharger has a half-split structure in which the generator housing 35 for storing a hollow cylindrical liner 42 and the stator disposed on the radially inner side of the liner 42 therein is split in half on a plane including a rotational axis of a rotor shaft. The exhaust turbine supercharger is equipped with: a hole 45 for supplying a cooling medium to a passage 43 formed inside the liner 42, and a hole for discharging the cooling medium from the passage 43, both holes being formed inside the generator housing 35; and a ring-like member 49 having a surface 49a opposing the liner 42 and a back surface 49b opposing the generator housing 35, both the surfaces being provided at each joint with the passage 43, and a through-hole 50 for communicating the hole 45 and the passage 43, or a through-hole 50 for communicating the discharging hole and the passage 43, at the center part.
