A turbocharger includes: a suction passage into which a fluid is sucked from outside of a compressor housing; an outlet passage that guides the fluid, which is sucked through the suction passage and compressed, to the outside of the compressor housing; an opening portion formed in a wall surface of the compressor housing and serving as an opening of the suction passage; a return passage which makes the outlet passage and the suction passage communicate with each other through the opening portion, thereby returning the compressed fluid from the outlet passage to the suction passage; and an air bypass valve which opens and closes the opening portion. A level of a bottom surface of the return passage located on a vertically lower side therein declines from the outlet passage toward the suction passage without ever rising. |
