The main part of this code lock will be described with reference to FIG. As shown in the drawing, a latch 51 whose front end is engageable with the door 50 is rotatably supported by a shaft 52, and the gear plate 53 is rotated as the latch 51 rotates.
Also, a shaft 55 that slides in the axial direction via the rack 54 rotatably supports the three discs 56 and the three ring-shaped wheels 57 with reference numerals on the outer peripheral surface. The disk 56 slides with the shaft 55, and the sliding of the character ring 57 with respect to the shaft 55 is restricted.
