Abstract: A storage box includes a bottom plate, a left-side plate, a right-side plate, a front-side plate, and a rear-side plate which surround to form a receiving space with an upper opening. The front-side plate opposite to the rear-side plate has a first section and a second section which are connected. A minimum distance between a top edge and a bottom edge of the front-side plate is smaller than a minimum distance between a top edge and a bottom edge of the rear-side plate. The left-side plate and the right-side plate are connected to the first section. A top edge of the left-side plate and a top edge of the right-side plate slope downward from the rear-side plate to the front-side plate and intersect at two points of the front-side plate. The front-side plate is divided into the first section and the second section by a line between the two points. The second section is located above the first section.
