Double scroll turbine and turbocharger

A double scroll turbine comprising:

• a turbine housing formed with two double scroll-type scroll flow paths configured to guide exhaust gas to a turbine wheel and a discharge flow path for discharging the exhaust gas that has passed through the turbine wheel,
• wherein the turbine housing includes
• a communication flow path wall that defines a communication flow path that allows the two scroll flow paths to communicate with each other, and
• a bypass flow path wall that defines a bypass flow path for guiding the exhaust gas flowing through the communication flow path to the discharge flow path while bypassing the turbine wheel,
• the communication flow path wall is formed with an outlet that guides the exhaust gas flowing through the communication flow path to the bypass flow path,
• the double scroll turbine further comprises a valve device, and
• the valve device includes
• a valve rod that extends to cross the communication flow path and that has an axis provided to pass through the outlet,
• a first opening/closing plate that is attached to the valve rod to extend along the axis and that is for opening/closing the communication flow path with rotation of the valve rod, and
• a second opening/closing plate that extends in a direction intersecting the axis, is attached to the valve rod on a side closer to the outlet than the first opening/closing plate, and is for opening/closing the bypass flow path with the rotation of the valve rod.
