Beschreibung
Zusammenfassung:	PURPOSE: A shift lock apparatus for an electronic transmission is provided to use a noiseless piezoelectric linear actuator for operating a stopper, thereby effectively removing the noise generated by operation of a solenoid. CONSTITUTION: A piezoelectric linear actuator (100) comprises a piezoelectric substrate (110), a vibration substrate (120), a moving shaft (130) and a movable unit (140). A locking unit is configured to interrupt the movement of a shift lever with the piezoelectric linear actuator. The locking unit comprises a push arm (210), and a stopper (220) coupled to the push arm by a hinge. The push arm reciprocates in a straight line by the piezoelectric linear actuator. The stopper rotates in the clockwise direction by a fixing axis. The control unit applies a driving voltage to the piezoelectric linear actuator according to operations of a change gear and a brake pedal.
