Abstract: An operation mechanism of a turbocharger includes: a driving member undergoes a reciprocating movement; a link plate rotationally coupled to the driving member through a first hinge-portion, wherein a first rotation-center of the first hinge-portion is moves linearly along a virtual line in a reciprocating manner in response to the reciprocating movement; and an operation lever. The operation lever includes: a first end operates a flow regulator of the turbocharger, wherein a swing center of the operation lever is located at the first end; and a second end rotationally coupled to the link plate through a second hinge-portion including a second rotation-center, wherein the second end is swings relative to the swing center when the first rotation-center moves linearly along the virtual line, and wherein a distance from the swing center to the second rotation-center is shorter than a distance from the swing center to the virtual line.
