This makes it easy to use A person applies a force to the release member 202 through the operation portion 202a, and deflects the release member 202 by an angle (as shown in Figs. 21 and 22) for operating the other end 72b of the elastic member 72 to move the first structure. The hook 74 of 32 can be separated from the second structure 34. In other words, the user does not need to put his hand into the rack or the second rail 30 to release the latching relationship between the first structure 32 and the second structure 34, so that the second rail 30 can be opposed from the extended position E. The first rail 28 is folded into the rack toward the second direction D2. It can be seen that the release member 202 can operate the elastic member 72, so that the hook 74 of the first structure 32 can be released from the second structure 34 (for example, a hole). Preferably, it further includes a returning elastic member 209, and the release member 202 can maintain the elastic force of the returning elastic member 209 at a predetermined position (such as the state of FIG. 19).

As shown in FIG. 23 and FIG. 24, the latching relationship between the first structure 32 and the second structure 34 can be released by the release member 202 of the second embodiment described above. In addition, the latching relationship between the first structure 32 and the second structure 34 can also be released through the third rail 36. In this implementation, for example, one of the third rail 306 and the first structure 32 has a release portion 81. Here, the synchronization feature 82 of the third rail 306 has the release portion 81 (for example, Bevel or arc). When the third rail 36 is displaced relative to the second rail 30 from the fully extended position Y toward the second direction D2 to a predetermined folding stroke, the third rail 36 can drive the first structure through the release portion 81 32 is detached from the second structure 34 to release the latching relationship between the first structure 32 and the second structure 34, so that the second rail 30 can be retracted from the extended position E relative to the first rail 28 to the aircraft. Inside the rack.
