The present invention relates to an actuator for a turbocharger. The actuator for a turbocharger comprises: a housing which is connected to a pneumatic transmission line, which is connected to an intake pipe of an internal combustion engine and applies air pressure, and in which a rod through hole is formed on one side thereof; a diaphragm lifted by the air pressure applied to the housing; a spring for elastically supporting the diaphragm; a rod which performs a reciprocal motion in accordance with the elevation of the diaphragm by being fixedly installed in the diaphragm, and opens and closes an exhaust passage switch for bypassing exhaust gas in an exhaust pipe of the internal combustion engine; and a rod guide bush having a ring-shaped body and including a hollow portion, which is formed on one side of the body and guides the rod to reciprocate by passing therethrough, and a coupling protrusion which is formed on the other side of the body and fixates the body by passing through the rod through hole. |
