Claims

[Claims for Utility Model Registration] (1) An air supply passage divided into two for feeding exhaust gas from an internal combustion engine to a turbine wheel, and a bypass passage each communicating with the air supply passage through a set of bypass bleed ports. a set of bypass valves that can be seated on the valve seats of each bypass bleed port; and a valve support body in which the set of bypass valves are supported via mounting members that are penetrated and attached at symmetrical positions across the center. An exhaust bypass device for a turbocharger, comprising: and an arm member that supports the valve support so as to be slightly displaceable in the closing direction of the bypass valve. (2) The bypass device according to claim 1, wherein the valve support and the arm member are connected through an arcuate surface.
