However, in the above-described structure, loading and unloading of carts to and from the packing box is limited to only the rear of the packing box. For example, even if it is desired to unload only the cart at the back of the packing box, There is a problem that the cart can only be removed after all carts located behind the cart have been lowered. As a means for solving this, there is a method of notching or opening and closing the side of the packing box. In the former case, since the side of the packing box is opened, there is a danger that the cart may fall from the opened part due to vibration or the like during traveling. The latter has a drawback that a great deal of labor is required since the entire side of the packing box must be opened and closed even when a single cart is unloaded. In view of the above, the present invention provides a cart carrier characterized in that cart loading and unloading operations can be performed in a short time with a small amount of labor.

[0005] This makes it possible to reliably prevent the cart from dropping from the side of the packing box. In addition, the cart can be unloaded and unloaded from the side of the packing box with a forklift or the like by attaching and detaching the regulating member, so that the unloading operation of the cart can be performed efficiently and in a short time. Further, only the regulating member corresponding to the cart to be unloaded when unloading from the side of the packing box needs to be removed, so that the labor of the operator can be minimized.

According to a second aspect of the present invention, a loading box capable of accommodating a plurality of carts is mounted on a vehicle body, and the loading box forms a frame frame by fixing upper and lower frames to supporting columns erected in front, rear, left and right. In addition, a lower floor surface is provided between the left and right lower frames, and in a cart carrier capable of loading a cart into the packing box from the rear or side of the packing box, a loading table lifting device is provided at the rear of the packing box, A plurality of regulating members are detachably mounted between the upper and lower frames on the side of the packing box with a smaller interval than the cart.

[0007] Thus, the loading / unloading operation of the cart can be performed from the rear of the packing box by the loading / unloading device and from the side of the packing box by a forklift or the like, and the work can be performed in a short time with a small amount of labor. In claim 3, the regulating member is
Provide upper and lower engagement members that can be engaged with the engaged portions of the upper and lower frames at the upper and lower ends in a long shape,
When the engaging member is engaged with the engaged portion, the engaging portion of one of the engaging members is made movable.

[0008] Accordingly, the attachment and detachment of the regulating member can be performed only by operating the regulating member alone, and the attaching and detaching operation of the regulating member can be performed in a short time. In claim 4,
The engaging portions of the upper and lower engaging members are formed in a convex shape so as to be able to engage with the concave engaged portions on the upper and lower frames, and the upper engaging portion of the upper engaging member is formed of a regulating member. It is characterized by being movable along a line. Thereby, when the worker grabs the regulating member and gets on and off the packing box, a downward external force acts on the regulating member, but the upper engaging portion of the regulating member is not moved only by the downward external force. In addition, it is possible to reliably prevent the risk that the regulating member comes off and the worker is injured.
