On the other hand, in the second embodiment, a “linear” hole for inducing the rotational movement of the hook 3 is formed in the slide member 2, and the “1” for inducing the rotational movement of the hook 3 in the structure 1. An “arc-shaped” groove is formed. That is, the rotational movement of the hook 3 is realized by combining a linear groove or hole formed in one member and an arcuate groove or hole formed in the other member.

  Since the hook 3, the two interlocking shafts 4, the engaging portion 6, and the operating means 5 can be the same as those in the first embodiment, description thereof is omitted here.

  At the time of locking, the two interlocking shafts 4 move along the shape of the guide hole of the slide member 2 and the shape of the guide groove of the structure 1 as the slide member 2 moves linearly. Arrows A and B shown on the slide member 2 in FIG. 14 represent the paths when the interlocking shaft a4a and the interlocking shaft b4b of the slide member 2 are locked, respectively. In addition, arrows A ′ and B ′ shown in the structure 1 in FIG. 16 represent the tracks when the interlocking shaft a4a and the interlocking shaft b4b in the structure 1 are locked, respectively. Note that the orbits (arrows A and B) when the interlocking shaft a4a and the interlocking shaft b4b in the slide member 2 shown in FIG. 14 are locked are relative to the interlocking shaft a4a and the interlocking shaft b4b associated with the linear movement of the slide member 2. It shows a typical trajectory. The common points between the first embodiment and the second embodiment are that, in the first embodiment, as shown by an arrow B ′ in FIG. 6, the interlocking shaft b4b is in the horizontal direction (FIG. ) On the other hand, in the second embodiment, as indicated by an arrow A in FIG. 14, the interlocking shaft a4a moves in the horizontal direction (FIG. 14, left and right direction on the paper) during the rotational movement. Thus, a hole or a groove is formed in the structure 1 or the slide member 2 so that the interlocking shaft a4a or the interlocking shaft b4b can move in the horizontal direction during the rotational movement. Thereby, the rotational movement of the hook can be realized without separately specifying the shape of the interlocking shaft a through-hole 3a or the interlocking shaft b through-hole 3b formed in the hook 3.
