ガタツキも強力抑えられる。A second aspect of the present invention is a specific embodiment of the rotation support structure at the lower end portions of both ends of the protective fence. Supporting plates in the vertical direction are provided so as to project on the side surfaces of the box body corresponding to the lower ends of both ends of the protective fence, and pins are provided laterally on the upper surface of one side of the supporting plate, and the same as the pins on the lower side edges of the supporting plate. Provided with laterally-direction locking pieces, and vertically forming long holes in which the pins fit and slide at the lower ends of both ends of the protective fence, and the locking pieces are provided near both ends of the long holes. When the protection fence is in the upright state, the pins engage with the upper ends of the elongated holes, and the lower protrusions engage with the locking pieces. When the protection fence is suspended and the protection fence is suspended, the pin engages with the lower end of the elongated hole and the upper protrusion engages with the locking piece to suspend the suspension. In this state, a structure is adopted in which the side surface of the box is stored and fixed.
According to the above configuration, the rotation of the protective fence is performed by rotating the pin in the long hole as an axis, and the rising and the suspended state are fixed by the pin, the long hole end, and the locking piece. Since it is maintained by engaging at two points with the protrusion, rattling of the protective fence is also strongly suppressed.

ように設けてなる構成を採用したものである。The invention of claim 3 is another embodiment of the rotation support structure at the lower end portions of both ends of the protective fence. A bearing is provided on the side of the box that corresponds to the bottom of both ends of the protective fence, the shaft hole of this bearing is aligned with the shaft hole at the bottom of both ends of the protective fence, and pins can be inserted into both shaft holes to freely rotate the protective fence. Mounted on the protective fence, and insert a spring for urging the protective fence in the axial direction of the pin between the shaft hole portion and the bearing, and when the protective fence is in a standing state or in a suspended state. At this time, a suspension piece for suspending the protective fence by the biasing force of the spring is vertically separated from the bearing and is provided so as to be suspended on the protective fence surface on the opposite side to which the spring is inserted. .

よる不快な振動音を防止することができる。According to the above construction, when the protection fence is raised from the suspension fixed state and projected above the upper surface of the box, the protection fence starts to rotate like a chain line against the biasing force of the spring. The spring bends and the protective fence rotates beyond the lower suspension piece, and then normally rotates without resisting the biasing force of the spring. It hits the stop, but at this point, if it is pushed harder, the spring will bend and the guard will move axially of the pin and will fit into the suspension and be suspended. When suspended, the protective fence is constantly pressed against the suspension piece side by the spring, so that an unpleasant vibration noise due to vibration during transportation can be prevented.

A caster is provided at the bottom of the box, and the caster is attached to the bottom of the box. It is configured so that it can be moved up and down. With the above configuration, when the cool box is placed on the floor, all the casters are stored at a position above the bottom surface of the box body, and the bottom surface of the box body directly contacts the floor surface to keep the cool box. Will not move. Further, when moving the cool box, the casters can be pushed out from under the box to facilitate the movement of the cool box and the loading and unloading of the cool box.
