Therefore, the receiving body on which the agricultural product is placed is elastically deformed in accordance with the form of the agricultural product to form a large number of contact surfaces, thereby stably holding the agricultural product. When the receiving seat body is subjected to an impact such as vibration during transportation and contact between the trays in addition to the weight of the agricultural product, the receiving seat body is appropriately bent by the synergistic effect of the receiving seat body and the hollow chamber. The impact is absorbed and can be reliably held without impacting the produce. Accordingly, there is an effect that agricultural products of various sizes and shapes can be stably placed on the tray.

Further, in the present invention, a plurality of reinforcing ribs extending radially from the center of the bottom wall are provided on the inner side of the tray body so as to partition the cavity chamber in plan view, If the back surface side of the receiving seat body and the upper surface of each reinforcing rib are configured to face each other at an appropriate interval, it is ensured that the receiving seat body that is elastically deformed by placing agricultural products may come into contact with each reinforcing rib. Can be suppressed. Therefore, while the rigidity of the saucer body is improved, there is an effect that it is possible to maintain the stable holding and shock absorbing action of the receiving seat body.
