Abstract
PURPOSE:To weaken the spring force of hook by making the direction of a straight line connecting the contact between a hook and a stopper pin and the axial center of supporting shaft of said hook to coincide with the direction of a backward rocking motion of the stopper pin started near the position where a tail gate is closed. CONSTITUTION:A hook 6 is installed on a packing box 3 swingably with a supporting shaft 7. Said hook 6 is connected to a stopper pin 8 provided on a tail gate 4, closing th tail gate 4. The rocking motion of the hook 6 is made by conveying the reclining motion of the packing box 3 through an operating arm 9 and a rod 15. When the hook 6 is engaged with the stopper pin 8 and the tail gate 4 is closed, the action line of belt F where the stopper pin 8 exerts its force to the hook 6 at the contact A, is arranged to cincide with the line L connecting the center B of the support shaft 7 to the contact A. Said operation arm 9 is forcibly rotated by a latch 20 fastened to a sub-frame 2 of a chassis in the early stage of reclining motion of the packing box.
