As shown in FIG. 4, when mounting the inner plate 4, when the inner plate 4 is fixed in the first recess 31 of the substrate 3 by a pair of screws 44 and 44 ', and when the inner plate 4 is in the desired vertical position, Screws pass through the holes 45, 45 'of the inner plate 4 and the upper slot 32, lower slot 32' of the substrate 3, respectively.

Also, as shown in FIG. 5, the outer plate 5 is fixed to the second recess 41 of the inner plate 4 by two screws 53 and 53 '.
And the outer plate 5 is in the desired horizontal position, these screws pass through holes 52, 52 'of the outer plate 5 and the upper slot 42, lower slot 42' of the inner plate 4, respectively.

FIG. 6 shows another embodiment of the present invention. In this embodiment, the vertically extending upper slot 32 and lower slot 32 'extend horizontally and the horizontally extending upper slot 42 and lower slot 42' extend vertically. The movement of the plate within each recess and slot varies correspondingly and will not be described in detail.

Although the present invention has been described with reference to the preferred embodiment, it is understood that many other possible variations can be practiced without departing from the scope and spirit of the claimed invention.

[0012]

As described above, the door lock according to the present invention is provided with the adjustable plate assembly in consideration of a large tolerance when mounting the lock case on the side end surface of the door. It can be adjusted so that the bolt and the receiving hole are always in a straight line, which causes the door to shift, bend,
Prevents dripping and other obstacles.
