Abstract
A housing for a turbocharger that makes it possible to prevent sticking of deposit and attain satisfactory assembling workability and easy moldability by die casting. The housing dividably includes a scroll piece and a shroud piece, including an annular refrigerant flow path defined by a first flow-path formation part of the scroll piece and a second flow-path formation part of the shroud piece. The first and second flow path formation parts are fitted with each other at inner and outer circumferential seal parts for sealing the refrigerant flow path on inner and outer circumferential sides thereof. The inner circumferential seal part is formed by press-fitting a first press-fitting portion of the shroud piece into a first press-fitted portion of the scroll piece. The outer circumferential seal part is formed by press-fitting a second press-fitting portion of the shroud piece into a second press-fitted portion of the scroll piece.
