PROBLEM TO BE SOLVED: To compactly fold the whole garbage collection box device when not in use by pivotably attaching an upper side plate to a back side plate in an openable/closable manner, forming right and left side plates in an inwardly foldable manner, providing a derricking mechanism to freely derrick a bottom side plate from the horizontal position to the position along the back side plate. SOLUTION: An upper side plate 5 is upwardly opened and oscillated to charge the garbage with an opening/closing handle part 5a when in use. When not in use, the upper side plate 5 is upwardly opened and oscillated, and a bottom side plate 4 is erected to the position along a back side plate 2 from the horizontal position by a derricking mechanism 9, and oscillated, and then, a front side plate 1 is moved toward the back side plate 2 while split plates 3a, 3b of the right and left side plates 3 are inwardly folded by hinged structures 7, 7. The upper side plate 5 is downwardly oscillated, and the upper side plate 5 is arranged forward of the front side plate 1 and folded there. In the derricking mechanism 9, a fulcrum shaft 10 is transversely provided on a lower part of the back side plate 2, the bottom side plate 4 is mounted on the fulcrum shaft 10, and a handle rod 12 is mounted on a projected end part of the fulcrum shaft 10. |
