Abstract
Provided is an exhaust turbine equipped with an exhaust control valve which can reduce wear of the contact surfaces between the shaft and the bushing or the turbine casing. The exhaust turbine is equipped with the exhaust control valve for opening/closing an exhaust bypass passage leading the exhaust turbine being driven by exhaust gas output from an engine to an exhaust outlet passage while bypassing the exhaust turbine, wherein the exhaust control valve comprises a shaft which is supported rotation-freely by a turbine casing and supports a valve element, an arm equipped with a connecting part with a drive source and turning the shaft about the axis thereof by the reciprocating motion of the connecting part produced by the drive source, and a weight attached to an end on the side opposite to the connecting part with the drive source with respect to the axis of the shaft.
