る。Now, when the operation plate portion 29 of each dial 27 is successively rotated by a desired angle by the fingertip operation to set an arbitrary unlock code string, as shown in FIG.
The movable element 33 rotates integrally with 7, and the positional relationship between the movable magnetic pole row 36 and the fixed magnetic pole row 38 of each movable element 33 changes. Therefore, the N magnetic poles 37N and S magnetic poles 37S of the movable magnetic pole row 36 are displaced from the S magnetic poles 39S and N magnetic poles 39N of the fixed magnetic pole row 38, and the movable magnetic pole row 36 and the fixed magnetic pole row 3 are displaced.
The magnetic attraction force acting between the movable piece 33 and the movable piece 33 tries to return the movable piece 33 to its original position.
Since a and the engagement hole of each dial 27 are in a strong engagement state by the spring force, the return rotation of each dial 27 is restricted.

いう効果を奏する。As described above, according to the present invention, when the unlocking code string of the dial mechanism is arbitrarily set and then the locking operation mechanism is operated, the dial returning mechanism is activated and the unlocking code string is deviated and locked. Since the mechanism is automatically set to the locked state, there is no need for a dial operation to shift the unlock code string in the locking operation, and even a person who is unfamiliar with handling can reliably generate the locked state and forget to lock. It has the effect of being completely preventable.
