Abstract
In a compressor housing, a scroll piece includes a cylindrical intake port forming section, a scroll wall surface forming section that forms an air-intake side wall surface of a discharge scroll chamber, and a scroll outer circumferential section that covers an outer circumferential side of the discharge scroll chamber. A shroud piece of the housing includes a cylindrical shroud press fitted section press fitted into the intake port forming section, and a shroud wall surface forming section that forms an inner circumferential side wall surface of the discharge scroll chamber and also forms a shroud surface that opposes an impeller and a diffuser surface. An outer circumferential annular piece of the housing includes an outer circumferential annular press fitted section press fitted inside the scroll outer circumferential section, and an outer circumferential annular wall surface forming section that forms an outer circumferential side wall surface of the discharge scroll chamber.
