Abstract
An exhaust-bypass valve capable of reducing wear of a rotating shaft to prevent controllability from deteriorating is provided. An exhaust-bypass valve () of a turbocharger includes a shunting passage () that communicates between a passage () at the turbine-inlet side and a passage () at the turbine-outlet side and a valve flap () that opens and closes this shunting passage (). The valve flap () opens and closes to shunt a gas flowing through the passage () at the turbine-inlet side into the passage at the turbine-outlet side. The valve flap () is rotatably supported at one side thereof serving as a center-of-rotation side, and the other side thereof moves away from or towards the shunting passage () to open or close the shunting passage (). A tapered portion () is provided at an edge on the other side. The edge is at least one of an edge of an opening of the shunting passage () facing the valve flap () and a side surface of the valve flap () facing the shunting passage ().
