<P>PROBLEM TO BE SOLVED: To accurately reduce the size of a compressor housing in the axial direction of an impeller rotation shaft even when forming the same by die-casting. <P>SOLUTION: The compressor housing 2a includes a scroll member 10 having an inlet part 11 and a flange part 15, and a shroud member 20 having a shroud part 21 and a fitting part 25 elongating from the shroud part 21 to the inlet part 11 to be fit onto an inner peripheral surface 11a of the inlet part 11. A reflux passage 2c includes an inclined part 16 opened to an inner peripheral surface 15a of the flange part 15 in a manner inclined with respect to an axial direction C to be closer to an impeller 2b, a dent part 17 formed on the inner peripheral surface 11a of the inlet part 11, and a counter part 25a facing the dent part 17 in the outer peripheral surface of the fitting part 25. The inside of the dent part 17 and the inside of the inlet part 11 communicate with each other through a communication part 17a formed with the dent part 17 and an end part 25b of the fitting part 25. <P>COPYRIGHT: (C)2013,JPO&INPIT |
