In this state, the extension portion 57 d of the first spring 57 contacts the wall portion 38 of the front reinforcing rib 32.
The latch device 23 is biased by the first spring 57 when the extension portion 57 d abuts against the wall portion 38. Accordingly, the latch device 23 rotates toward the holding wall 44 with the insertion portion 56 as an axis (about the axis 75 of the first insertion hole 36). That is, the contact portion 65 of the latch device 23 moves in the horizontal direction toward the holding wall 44.

As shown in FIG. 12, the contact portion 65 moves toward the holding wall 44, whereby the contact wall 66 of the contact portion 65 contacts the holding wall 44. At the same time, the engaging portion 67 is inserted into the engaged portion 45 by moving in the horizontal direction toward the engaged portion 45 (that is, the through hole).
When the engaging portion 67 is inserted into the engaged portion 45, the engaging portion 67 is engaged with the lower side 45 a of the engaged portion 45 from above. Therefore, the engaging portion 67 can be prevented from moving downward by the lower side 45a of the engaged portion 45. Accordingly, the latch device 23 (see FIG. 11) is temporarily held by the slide arm 25, and can be effectively prevented from falling off the slide arm 25.

Further, the contact portion 65 is urged toward the holding wall 44 by the first spring 57 (see FIG. 11). Therefore, the engaging part 67 can be prevented from moving in the horizontal direction away from the engaged part 45, and the engaging part 67 can be held by the engaged part 45.
Thereby, the latch device 23 can be easily temporarily held on the slide arm 25, and the attaching operation of the latch device 23 can be facilitated.

  In this way, the latch device 23 is temporarily held by the slide arm 25. In this state, the mounting hole 61 of the first housing part 52 and the mounting hole 62 of the second housing part 53 are arranged at positions away from the second insertion hole 37 of the arm upper wall 31.

Thereby, the workability | operativity at the time of inserting the latch apparatus 23 and the insertion part 56 in the 1st insertion hole 36 from the downward direction of the slide arm 25 improves.

  As shown in FIG. 14A, the extension 57 d of the first spring 57 contacts the wall 38 of the front reinforcing rib 32. Therefore, the latch device 23 rotates as indicated by the arrow B toward the holding wall 44 about the insertion portion 56 by the urging force of the first spring 57. As the latch device 23 rotates, the contact portion 65 of the latch device 23 moves in the horizontal direction as shown by the arrow B toward the holding wall 44.

  When the contact portion 65 moves, the contact wall 66 of the contact portion 65 contacts the holding wall 44, and the engaging portion 67 is inserted into the engaged portion 45 (that is, the through hole). As a result, the latch device 23 is temporarily held by the slide arm 25, and the latch device 23 can be prevented from falling off the slide arm 25.

As shown in FIG. 14B, in a state where the latch device 23 is temporarily held by the slide arm 25, the latch device 23 is rotated as indicated by an arrow C with the insertion portion 56 as an axis.
