That is, the hook 105 slides inside the case 101 together with the slider 104 (on the right side in FIG. 6D). At the same time, the hook 105 further rotates counterclockwise with respect to the slider 104. The outer surface 105 a of the hook 105 reaches a predetermined position P outside the case 101. The tip 105b of the hook 105 is caught by a receiving seat 137 provided on the fitting 302 side.

  FIG. 6E shows a state (locked state) where the sliding door 301 is locked by the hook 105 continuously from the state shown in FIG. 6D.

  As shown in FIG. 6E, when the operation members (the first drive member 102 and the second drive member 103) are further rotated clockwise, the hook 105 further slides inside the case 101 (on the right side in FIG. 6E) The hook 105 further rotates counterclockwise with respect to the slider 104. As a result, the front end 105b of the hook 105 draws the first face seat 130 provided on the sliding door 301 side into contact with the receiving seat 137 provided on the fitting 302 side.

  FIG. 7 is a schematic diagram showing the main constituent members of the kama tablet 100 of FIGS. 6A to 6D in an overlapping manner.

  As shown in FIG. 6A, even if there is a slight gap between the first face seat 130 provided on the sliding door 301 side and the receiving seat 137 provided on the joinery 302 side, As shown in FIGS. 6C and 7, the hook 105 can be sufficiently projected outside the case 101. As a result, as shown in FIGS. 6D and 7, the kama lock 100 can sufficiently hook the tip 105b of the kama 105 on the seat 137 provided on the joinery 302 side. Therefore, as shown in FIG. 6E, the paddle lock 100 draws the first face seat 130 provided on the sliding door 301 side to the receiving seat 137 provided on the fitting 302 side by the tip 105b of the paddle 105 and makes contact. be able to.
