Claims

[Claims for Utility Model Registration] 1. Two scroll passages extending in parallel in the circumferential direction are formed in the turbine housing, a bypass passage is connected to each of the two scroll passages, and a bypass control valve is provided in each of the bypass passages. place,
A bearing provided in the turbine housing has each end protruding to support a support shaft, and each of the bypass control valves is attached to one end of the support shaft via a common arm member to determine the longitudinal positional relationship of the support shaft. Connect with
In the exhaust bypass device for a turbocharger in which a drive mechanism for a bypass control valve is connected to the other end of the support shaft, the support shaft is connected to the support shaft such that the common arm member has an axis that is inclined with respect to the axis of the support shaft. A turbocharger exhaust bypass device characterized by being welded and fixed to. 2. The arm member has a cylindrical part fitted to the support shaft, and the clearance between the cylindrical part and the support shaft is larger than the clearance between the bearing and the support shaft, and the cylindrical part 2. The exhaust bypass device for a turbocharger according to claim 1, wherein the exhaust bypass device is fitted onto the support shaft and fixed by welding in an inclined relationship.
