Then, the auxiliary lever 86 connected to the connecting lever 88 via the connecting bar 87 rotates in the unlocking direction. At this time, the abutting portion 86 </ b> A provided in the sub-lever 86 rotates while abutting against one stopper 84 </ b> A provided in the interlocking lever 84. That is, the interlocking lever 84 rotates together with the sub lever 86. Then, the unlocking operation force F <b> 1 is transmitted to the locking device 40 of the left door 11 through the second flexible cable 47 connected to the interlocking lever 84. Further, as the interlocking lever 84 rotates, the first linear motion member 82 advances toward the mechanism portion 60 of the right door 11 and is pushed by the first linear motion member 62, so that the right mechanism portion 60 The second linear motion member 63 moves backward. As a result, the right interlocking lever 64 also rotates in the unlocking direction, the second flexible cable 47 is pulled, and the unlocking operation force F1 is transmitted to the locking device 40 of the right door 11, and the first flexible When the cable 27 is pushed, the unlocking operation force F <b> 1 is transmitted to the unlocking device with locking unit 20. Each locking device 40 that has received the unlocking operation force F1 is unlocked as described above. Further, as shown in FIG. 7, the unlocking operation unit-equipped locking device 20 receives the unlocking operation force F <b> 1 and the release lever 25 rotates, and the lock member 24 also rotates accordingly. As a result, the engagement between the locking claw 24N of the lock member 24 and the locking projection 22T of the latch 22 is released and the unlocked state is established. Thereby, all the locking parts with which both the doors 11 and 11 were equipped are unlocked also by the unlocking operation of the unlocking operation apparatus 30 of the left door 11.

  Thus, according to the present invention, even if the unlocking operation unit locking device 20 or the unlocking operation device 30 of any of the doors 11 and 11 is unlocked, the unlocking operation force F1 is a pair of mechanism units. It is transmitted between 60 and 80, and the locking device (20, 40) of both doors 11 and 11 can be unlocked at a time. Moreover, since the 1st and 2nd flexible cables 27 and 47 with high flexibility were used in order to transmit the unlocking operation force F1, the mechanism parts 60 and 80 in each door 11, 11 and the unlocking operation device 30, The freedom degree of arrangement | positioning between the unlocking operation part locking apparatus 20 and the locking apparatus 40 increases. Moreover, after attaching the mechanism parts 60 and 80, the unlocking operation apparatus 30, the unlocking operation part locking apparatus 20, and the locking apparatus 40 to each door 11 and 11, by adjusting the position of the cable bracket 29, Since the unlocking operation force F1 can be accurately transmitted, the mechanisms 60 and 80 and the unlocking operation device 30, the unlocking operation unit-equipped locking device 20, and the lock in the doors 11 and 11 are further improved. The freedom degree of arrangement | positioning with the apparatus 40 increases.
