(See FIG. 5).

  After the right door 2A is opened, when the hand is released from the handle 21 and the pressing is released, the transmission shaft 3 receives a spring force from a return spring (not shown) and rotates in the opposite direction. It rotates integrally and returns to the original state (the state indicated by the alternate long and short dash line in FIG. 5). When the right door 2A is closed in this state, the cam surfaces 36 of the latches 31 and 32 abut against the latch receiving portions 11 and 12 and are pressed, so that the latches 31 and 32 are rotated by the pressing force. When the hook-shaped portion 35 passes through the openings 15 and 16, the latches 31 and 32 are restored by receiving the spring force of the return spring, and are thereby engaged and restrained by the latch receiving portions 11 and 12. The door 2A and the left door 2B are held closed.

  When the right and left doors 2A and 2B are closed, when the unlocking code string of the code lock device 4 is in the aligned state, the knob 42 for turning operation is located between the locking position X and the unlocking position Y. It can be turned in either forward or reverse direction. When the knob 42 is turned and set to the locking position X, the drive plate 6 is tilted and the engagement groove 61 of the operating portion 63 and the transmission shaft 3 are engaged (the state shown by the one-dot chain line in FIGS. 9), the rotation of the transmission shaft 3 is restricted. Even if the handle 21 is operated in this state, since the rotation of the transmission shaft 3 is restricted, the latches 31 and 32 do not rotate but engage with the latch receiving portions 11 and 12 of the rocker body 1. The doors 2A and 2B are kept closed while being restrained. Next, when the unlocked code string is broken by operating the four dials 41, the code lock device 4 enters the locked state, and the knob 42 cannot be turned from the locked position X to the unlocked position Y.

  When opening the doors 2A and 2B, by operating the four dials 41 and aligning the unlocking code string, the code-locking device 4 is unlocked, and the knob 42 is turned from the locking position X to the unlocking position Y. The unlock position Y can be set. When the knob 42 is set at the unlocked position Y, the engagement groove 61 of the operating portion 63 of the drive plate 6 and the transmission shaft 3 are disengaged, and the rotation restriction of the transmission shaft 3 is released. When the handle 21 is operated in this state, the transmission shaft 3 rotates and the latches 31 and 32 rotate integrally therewith, whereby the latch receiving portions 11 and 12 corresponding to the latches 31 and 32 and the locker body 1 are rotated. And the right door 2A can be opened.
