1. An operation mechanism of a turbocharger, the operation mechanism comprising:
a driving member configured to undergo 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 configured to move linearly along a virtual line in a reciprocating manner in response to the reciprocating movement of the driving member; and
an operation lever including:
a first end configured to operate 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 of the operation lever is configured to swing 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 always shorter than the shortest distance from the swing center to the virtual line.
