And a slide lock 4 which is driven by the lock lever 2 and moved up and down by a guide rail 3 formed in the door lock body to be locked to the locking member (not shown), and the door lock body 10. A plurality of stoppers (5) formed in the center and defining a rotation of the lock lever (2), a torsion spring (6) applying a tension force to the lock lever (5) and applying a rotational movement to the lock lever (5); , Lock button (7) is installed on one side of the door lock body to restrain the movement of the lock lever (5) to maintain the locked state of the slide lock (4).

And the key bundle is composed of a rotary body 20 and the cylinder body 30 as shown in Fig. 1 and 2, the key insertion port 11 is inserted into the key 16 is inserted into the front surface and the projection pin on the upper surface Rotating body 20 having a certain number of inserting pin insertion hole 13 into which the 12 is inserted and having an operating tool 14 and an operating plate 15 which rotate in correspondence with the operation of the rotating body, The hollow 21 is formed for the passage in which the whole 20 is inserted, and the top surface 20 is inserted into the insertion hole 13 of the rotating body 20 (hereinafter, 20 is referred to as a key bundle) to limit the rotation of the rotating body. It consists of a cylinder body 30 with a pin 12 embedded therein.

Looking at the operation of the key bundle in the normal state, because the exit pin 12 embedded in the cylinder body 30 is maintained in the insertion hole 13 of the rotating body 20 is not inserted into the key 16 The rotating body 20 cannot be operated and thus the door lock state is maintained.

Then, when the key 16 is inserted into the rotating body 20, according to the concave-convex portion 17 of the key 16, the projecting pin 12 overcomes the spring 22 force and rises at a constant elevation angle, and the projecting pin ( When the broken portion of 12) is located between the rotor 20 and the cylinder body 30, there is no more resistance to prevent the flow of the rotor 20, thereby rotating the rotor 20, thereby releasing the door lock.
