The tailgate 10 having the support partition wall 11 formed thereon is formed on both sides, and a plurality of rollers 40 are rotatably fixed to the handle 20 and the sidewalls on both sides thereof, and the tailgate 10. Locking jaws 61a and 61b are formed at the rear end of the inner circumference of the guide hole 14 and the outer one side of the guide hole 14 in order to restrict the left and right movements while being inserted into the guide hole 14 of the guide hole 14. Fixture (60) protruding from the fixing protrusion (62), and one side of the rear of the fixture (60) The spring 70 is elastically interposed between the support bulkheads 11 so that one end is drawn out to the center of the rear end of the fixture 60 and the other end is inserted into the insertion hole 12 of the support bulkhead 11 to tension the roller 40. Both side fixing projections 62 of the fixture 60 connected to the handle 20 and the wire 30 by the pulling operation of the handle 20 and the wire 30 by the pulling operation of the handle 20 are wound in the state of the guide groove 51. Simultaneous removal and insertion from the fixing hole 52 allows the tailgate 10 to be easily moved and fixed in the longitudinal direction of the loading box.

According to the present invention, when the size of the cargo is small or the height of the cargo does not exceed the height of the tailgate 10, the tailgate 10 is loaded along the guide frames 50 installed inside both sidegates. By moving the tailgate 10 is in close contact with the cargo easily, it is possible to prevent the fast fixation of the cargo as well as damage to the cargo.

The present invention is a guide formed on the inner top, bottom of the guide groove 51 in which a plurality of fixing holes 52 are formed at equal intervals in the longitudinal direction at the inner center so that the tailgate 10 can be moved and fixed step by step. The frame 50 is installed to face the inside of the side guide.

The fixing protrusion 62 of the fixture 60 is always inserted into the fixing hole 52 of the guide frame 50 while being supported by the rear locking jaw 61a61b at the center of both side projections 13 of the tailgate 10. The spring 70 is elastically interposed between the rear of the fixture 60 and the support partition wall 11 so as to maintain the state.
