Claims

[Scope of utility model registration request]

A bypass passage is connected to each of the plurality of scroll passages formed circumferentially in the turbine housing, a bypass control valve is arranged in each of the bypass passages, and each of the bypass control valves is fitted into a bearing provided in the turbine housing. In the exhaust bypass device for a turbocharger, the bypass control valves are connected to a support shaft via a common arm member in a positional relationship in the longitudinal direction of the support shaft. and a second arm member fixed to the support shaft, the first arm member and the second arm member being connected so that they can move relative to each other within a limited range. An exhaust bypass device for a turbocharger.
