Abstract
In a compressor for a supercharger of an internal combustion engine comprising a shroud, an impeller, a vaneless diffuser, and a scroll, a hub-side wall of the vaneless diffuser is formed to be inclined to the opposite side to a shroud-side wall with respect to a direction perpendicular to a rotational axis of the impeller in the longitudinal cross section including the rotational axis of the impeller. With such a configuration, the amount of deposit formed on the hub-side wall of the vaneless diffuser is reduced.
