Abstract
Provided are a variable geometry turbine and a supercharger including the same that can change flow rate characteristics of a turbine in accordance with engine output with simple structure and can adjust the flow angle of a fluid flowing into a turbine impeller to any angle in the circumferential direction of the turbine impeller. The variable geometry turbine () includes a turbine impeller () configured to rotate about an axis line, a turbine housing () configured to accommodate the turbine impeller () and form a throat passage () and a scroll flow channel () on the outer circumferential side of the turbine impeller (), the scroll flow channel () communicating with the throat passage (), and a width changing mechanism in which a width change portion () that changes a passage width of the throat passage () along the circumferential direction of the turbine impeller () is movable in the width direction of the passage width.
