A supercharger is provided with a turbine housing (4) in which an internal space (S1) is formed, a bearing part (22) provided to the turbine housing (4), a shaft (23) rotatably inserted in a bearing hole (22a) such that at least one end protrudes farther into the turbine housing (4) than the bearing part (22), and a valve (16) for opening and closing a flow channel that opens into the internal space (S1). The bearing part (22) has a protruding part (22b) that protrudes from the inner wall of the turbine housing (4). A diameter hole (22d) of the protruding part (22b) passes through the bearing part (22) in the diametrical direction of the shaft (23), from the outer peripheral surface (22c) of the bearing part (22) to the bearing hole (22a). |
