ABSTRACT:
A driving mechanism is disposed in the bottom of a door for driving the door and includes a reduction gearing and a motor fixed to the door, and a gear coupled to the reduction gearing and engaged with two shafts for rotatably supporting the wheels of the door so as to apply a downward force to the pinions in order to prevent the wheels moving upward away from the tracks. A retaining device is fixed to one of the tracks or fixed to the ground and has an opening for engaging with one of the pinions so as to maintain the door in place.
