Further, since the number of packaging units per carton is small, a large number of cartons are required, which causes a drawback of increasing the packaging cost. Furthermore, as the carton is assembled (bottoming) and the interior pads are set, it takes time to perform the preparation work, and it takes time to unpack and take out parts, and the used packaging materials are bulky. It was troublesome to clean up.

The present invention has been made in view of such an actual situation, and an object thereof is to facilitate a preparatory work, to reduce a packing volume and a packing cost, and to keep the original packing state in a local factory. It is to provide a multi-stage packing box that can be transported to the line side.

[0005]

In order to solve the above-mentioned problems of the prior art, according to the present invention, a box-shaped upper part having a shelf separately formed therein and accommodating a plurality of parts is provided therein. A lower frame and a middle shelf arranged in the middle of the upper and lower frames are provided. While the holder is fixed to the upper frame, the locking member is fixed to the middle shelf, and the upper shelf is provided on the lower frame. While fitting the middle shelf supported by the locking member,
The lower frame is configured to be assembled by stacking the upper frame with a holder.

[0006]
