SOLUTION: This lock device R attached to a door 1 installed in a storage section and capable of locking/unlocking the door 1 comprises a cylinder lock 2 attached to the rear surface of the door 1 with a mounting member 3 interposed therebetween while a key hole is exposed to the front side of the door 1, a latch 4 attached to a working body for unlocking of the lock 2, a latch operation control member 7 for allowing the latch 4 to move to the operation end of the latch 4 or for stopping the operation of the latch 4 before the operation end in unlocking. By operating the control member 7 attached to the mounting member 3, the latch operation in unlocking can be set selectively between a state in which the key can be extracted from the cylinder lock 2 and a state in which the key cannot be extracted.
