ABSTRACT:
The cylinder lock according to the present invention comprises a latch 19 movably disposed between the joint position connecting the key cylinder 16 and a driver 18 and the release position disengaging the key cylinder 16 and a driver 18; and a clutch 20 for transferring the latch 19 to the release position when a sleeve 13 rotates relatively to a housing 11 with an improper key. When a proper key is inserted into the key cylinder 16, it can be rotated without rotation of the sleeve 13 so that the driver 18 can be rotated to the locked or unlocked position through the latch 19 which drivingly connects the key cylinder 16 and the driver 18. When an improper key is inserted into the key cylinder 16 and rotated, the sleeve 13 is rotated with the key cylinder 16 through tumblers 17 so that radial movement of the clutch 20 disengages the latch 19 and driver 18, thereby preventing unauthorized unlocking of the cylinder lock 10 without rotation of the driver 18.
