However, the following examples are merely exemplary, various modifications are possible within the technical spirit of the present invention, and the present invention is not limited.

1 is a plan view of the mechanical locking device of the vehicle door device of the present invention, Figure 2 is a cross-sectional view taken along line AA in Figure 1, Figure 3 is a cross-sectional view taken along line BB in Figure 1 4 is a view showing an operating state.

The mechanical locking device 1 of the present invention is formed in an approximately center portion of a door engine installed in an upper portion of a sliding door, that is, in an upper predetermined space of both doors, and a double hook plate 10 having a hook formed at both ends and a fixing member. It consists of approximately 20, the intermediate plate 30, and the base plate 40 formed in the outermost side.

The double hook plate 10 is a flat plate having hooks 11 and 12 formed at both ends thereof. The hook 11 on one side is opened downward, and the hook 12 on the other side is opened upward. It consists of a substantially "S" shape, and is attached to be rotated by a predetermined angle of approximately 45 degrees. Further, as can be seen from FIG. 2, which is a cross-sectional view along the line AA of FIG. 1, the connector 13, the special key catching portion 14, the key groove 15, and the special portion face downwards of the double hook plate 10 located at the top. The key insertion port 16 and the base plate 40 described below are connected in sequence. Therefore, when the driver inserts a special key (not shown: a key owned by the driver of the vehicle), the tip of the special key is engaged with one side of the special key locking portion 14, and a rotational force (torque) is added to the special key. Then, the added rotational force rotates the special key locking portion 14 so that the rotational force rotates the double hook plate 10 approximately 45 degrees through the connector 13.

The fixing member 20 has a thickness such that a bolt is inserted as a substantially hexagonal cross section to fix another member, and a key groove 15 connected to the double hook plate 10 penetrates at one side thereof. The double hook plate 10 is supported, and a limit switch 21 for informing the driver of the opening / closing state of the door is mounted and fixed to the upper portion of the other side.
