PURPOSE:To move vertically a tail gate smoothly without being interfered with an engaging pin and a hook when the tail gate is pivoted to the horizontal position, by securing fixedly the engaging pin to the tail gate base to make said pin engage the hook pivotable in association with the vertical movement of a cargo box. CONSTITUTION:A tail gate 16 can be vertically moved by the operation of a hydraulic power unit through a linkage, while it can be opened and closed in association with the inclination of a cargo box 3. An U-shaped engaging pin 23 is secured fixedly to the base end of the tail gate 16 and a hook 26 is pivotably journaled 27 in the rear end of a main beam of the cargo box 3. When the tail gate 16 is received vertically on the rear surface of the cargo box 3, the hook 26 engages the engaging pin 25 to enable the gate 16 to be fixedly fastened. Also, the engaging pin 25 and the hook 26 are provided such that they do not interfere with each other in the vertical movement of the gate 16 with the upward movement of said pin 25 when the tail gate is pivoted to the horizontal position. |
