And a third gear 38 having a diameter smaller than the diameter of the second gear 36.

On the other hand, at the center of rotation, the operating gear 40 having the hub hole 46 provided with the gear protrusion jaw 42 is engaged with the third gear 38.

3 and 5, a hub hole 46 is formed at the center of rotation of the actuating gear 40 which transmits the rotational force of the drive motor 20 to the dead hub 50 to be described later. The hub hole 46 penetrates into a diameter corresponding to the dead hub 50, and a gear protrusion jaw 42 protruding inwardly a predetermined length toward the center thereof is formed to a predetermined thickness.

Further, the gear projecting jaw 42 is preferred to be formed so that the two are symmetrical with each other relative to the rotation center point of the center point In other words, the operation gear 40 of the hub hole 46, which rotation of the dead hub 50 to be described later By operating the bar 55 manually to prevent the external force is applied to the gear assembly 30 when the dead bolt 60 is moved forward and backward, the service life of the gear assembly 30 and the drive motor 20 is increased, At the time of automatic operation, the inertia is made by the interval between the gear projection jaws 42 of the operating gear 40 constituting the gear assembly 30 which receives the driving force of the driving motor 20, and thus, the rotation bar 55 is easy.
