An assembling structure for an intake manifold includes: a first downstream portion; a second downstream portion; an upstream portion; a connecting member that connects the first downstream portion and the second downstream portion with each other; and a plate-shaped stay. The connecting member is fixed to the first downstream portion and the second downstream portion by a bolt, and an other member that is a member other than the intake manifold is fixed to the intake manifold through the stay at least either between the connecting member and the first downstream portion, or between the connecting member and the second downstream portion.

Assembling structure for intake manifold

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.

A turbine housing includes an outer housing member, which has a proximal housing portion and a distal housing portion, and an inner housing member, which is provided inside the outer housing member and has a shroud surface that faces a turbine wheel in an axial direction. A distal portion of the inner housing member serves as a slide portion slidable in the axial direction. Further, a proximal portion of the inner housing member is fixed to the proximal housing portion at a part closer to a distal side than a proximal portion of the proximal housing portion. Further, a scroll portion is formed by the inner housing member and a proximal scroll portion of the proximal housing portion located closer to a proximal side than the inner housing member.
