PROBLEM TO BE SOLVED: To properly set the code unlocking row as intended by a user, even if the order of the setting operation of a code unlocking row is set before or behind the right place. SOLUTION: In a front plate 3, a knob 110 for driving an operation driving part 10, four dials 50 for setting 80 unlocking code row, and the push-button 31 of an operating device 30 or the like are arranged. After the setting of the unlocking code row is carried out by the operation of the dials 50, and the operation-driving part 10 is driven by the operation of the knob 110 to close a latch 1, when the push-button 31 of the operating device 30 is depressed, the set unlocking code row is stored in the memory, and thereafter, the alignment of the unlocking code row is collapsed and the locking condition is attained.
