Then, one end of the tightening link 15 is attached at a position slightly away from the connecting link 7 of the lock lever 14 so as to be rotatable in the horizontal direction.
[0012]
A slide lock pin support link 16 is attached to the other end of the tightening link 15 so as to be rotatable in the horizontal direction. An intermediate portion of the slide lock pin 8 is fixed to the distal end portion of the slide lock pin support link 16. Further, an intermediate portion of the slide lock pin 9 is pierced and supported by the intermediate portion of the slide lock pin support link 16 so as to be movable left and right. The movement of the slide lock pin 9 to the right is regulated by a nut (lock nut) 17 with a detent. The position is set to be slightly longer than the mounting span of the backlash preventing fastening hook 12 and the gate fastening hook 13. Further, a backlash prevention spring 10 is provided between the slide lock pin 8 and the slide lock pin 9.
[0013]
The position of the lock nut 17 can be adjusted by the spring pressure adjusting nut 11. Since the backlash prevention spring 10 is provided between the slide lock pin 8 and the slide lock pin 9, it can be adjusted according to the backlash of the tightening link portion by moving the tightening position of the spring pressure adjusting nut 11. it can.
