Provided is an electric waste gate actuator for a turbocharger, which includes a return spring for assisting a retention force of a final output gear, and a stopper for adjusting a rotation angle of the final output gear, thereby reducing an amount of a current consumed for maintaining the final output gear at a constant position. The electric waste gate actuator for a turbocharger includes: a housing having an installation space formed by a body and a cover; a driving motor installed within the installation space; a decelerator including gear trains provided with a plurality of gears, such that the decelerator is coupled to a lever installed outside the housing and transmits power of the driving motor; and an elastic member cooperating with the driving motor so as to maintain a rotation angle of a final output gear for finally transmitting power to the lever among the gear trains.
