1. A supercharger comprising:
a turbine housing including
a turbine room,a scroll passage communicating with the turbine room, andan exhaust-gas inlet portion connected to an exhaust system member placed on an upstream side of the turbine housing in an exhaust-gas flow direction, the exhaust-gas inlet portion including a scroll port and a bypass port, the scroll port being an inlet of the scroll passage, the bypass port detouring around the turbine room so as to communicate with a downstream side, in the exhaust-gas flowing direction, relative to the turbine room; and a pipe configured to cover an inner peripheral surface of the exhaust-gas inlet portion in a state where at least part of the pipe is distanced from the inner peripheral surface, the pipe including an inserted portion, the inserted portion being positioned in the exhaust-gas inlet portion of the turbine housing, the pipe having an inner passage branched into a first branch passage and a second branch passage on the downstream side in the exhaust-gas flowing direction, the first branch passage being connected to the scroll port, the second branch passage being connected to the bypass port, at least part of a pipe wall of the pipe being a part of the second branch passage, the at least part of the pipe wall of the pipe being distanced from the inner peripheral surface of the exhaust-gas inlet portion. |
