PROBLEM TO BE SOLVED: To provide a compressor housing for a supercharger, which has a simple structure and can be easily manufactured.SOLUTION: A compressor housing 1 has a housing body 20, an annular sliding member 30 forming a shroud surface 31, and a fixing member 4 interposed between the housing body 20 and the sliding member 30 and positioning and fixing them each other. The housing body 20 has a diffuser surface 24 formed on a plane surface orthogonal to an axial direction X on an outer peripheral side of the shroud surface 31. A sub-assembly made from the housing body 20 and the sliding member 30 is formed at a part on a boundary line between the diffuser surface 24 and the shroud surface 31 so as to cross the boundary line, and provided with a recessed space 5 opening to the diffuser surface 24 side. The recessed space 5 is filled with the fixing member 4. The recessed space 5 and the fixing member 4 have an expanding portion increasing a cross sectional area of a crosse section orthogonal to the axial direction as separating from an opening portion, on at least one place in the axial direction.SELECTED DRAWING: Figure 1 |
