The rotary shaft is supported by the casing. The impeller is rotatably fixed to the rotary shaft, and sends the gas radially outward to a flow path downstream thereof. The diffuser is formed around the impeller. The first scroll is formed around the diffuser. The second scroll is formed between the diffuser and the impeller. The first passage is formed from the impeller to the first scroll through the diffuser. The second passage is formed from the impeller to the second scroll. The switching member switches the flow path between the first passage and the second passage by opening and closing the diffuser.
