Claims

[Scope of utility model registration request]

a bearing housing that pivotally supports the center shaft; a turbine housing that accommodates a radial turbine impeller provided at the end of the center shaft; an annular inlet for inflowing exhaust gas toward the vehicle; and a plurality of annularly arranged annular inlets that are axially installed in either one of the housings facing the annular inlet and are oriented in the same direction as the center shaft direction. a support shaft; a nozzle vane provided at one end of the support shaft to vary the opening amount of the annular inlet; a lever provided at the other end of the support shaft and extending in a direction substantially perpendicular to the support shaft; an annular groove provided concentrically with the center shaft in either one of the housings, and an annular rotating portion that is rotatably fitted onto the annular groove and linked to a yoke portion formed at the rotating end of the lever. An exhaust supercharger, characterized in that a slider is attached to the rotating part, and the slider is slidably engaged with the yoke part in surface contact.
