A compressor 20 includes an impeller 30, a housing 32, and a connecting shaft 34. An inlet 36 for introducing gas into a suction side of the impeller 30, and an annular groove 38 formed in an outer periphery of the inlet 36 are formed in the housing 32. The groove 38 communicates with the inlet 36 on the intake passage 18 side. The groove 38 is blocked on the impeller 30 side. A gas outlet of an EGR passage 24 is connected with a middle of the groove 38. An inner diameter ID 38 of the groove 38 is machined to be larger than an inner diameter ID 18 of an end part of the gas outlet of the intake passage 18 (an end part on the inlet 36 side). |
