The present invention relates to an interval adjustment device adjusting the interval by moving a lock cylinder (1) and a handle lever (2) forward or backward according to the thickness of a door (D). The interval adjusting device comprises a lock cap (10) having a fastener (11) penetrated into the center so as to accept the lock cylinder (1) and a movable groove (15) moving the lock cylinder (1) forward or backward in the state of accepting the lock cylinder (1); a lever cap (20) having a fastener (21) penetrated into the center so as to accept a handle lever (2) and a movable groove (25) moving the handle lever (2) forward or backward; and an adjusting tool (30) adjusting the interval by automatically moving according to the thickness of a door with the lock cylinder (1) and the handle lever (2) mounted on the lock cap (10) and the lever cap (20) to be mutually interlocked. Accordingly, the present invention protects the lock cylinder and the handle lever from outside, provides various aesthetic feelings, improves the constructability and workability as the interval is able to be adjusted so as to install the lock regardless the thickness of a door, enables to reduce the manufacturing costs as a spring performing a pressurization function in adjusting the interval is formed as one body, and enables to drastically reduce the construction time with an excellent assembly property. |
