<p>The present invention relates to a shift actuator of an automated manual transmission which includes: a control finger for carrying out shift and selection actions by being retained to a shift lug; a shift driving motor having a driving shaft to which the control finger is connected; a selection cylinder which is connected to the control finger to slide the control finger from the driving shaft; a solenoid valve which is connected to the selection cylinder to prevent pressure from being transferred to the selection cylinder or to connect pressure to the selection cylinder; and a control unit for controlling the solenoid valve and the shift driving motor by shifting. Therefore, the shift actuator does not use a plurality of cylinders or a plurality of motors to carry out the shift and selection actions but realizes the shift action by the motor and the selection action by the cylinder so as to reduce manufacturing expenses of components because it does not use expensive motors for the selection action which does not requires precision.</p> |
