Abstract: A return device for a drawer employs an actuator to drive a slide block, when the drawer is pulled open, the slide block is moved into a positioning concave and positioned therein while stretching an elastic member. Or pushing the drawer back can make the slide block slide out of the positioning concave, meanwhile, the elastic member pulls the drawer back to its original position. Furthermore, since the angle between the slide surface of the positioning concave of the positioning member and the track is obtuse, it is easy for the slide block to slide in and out, so that the drawer can be easily positioned and unlocked from the positioned state.
