CONSTITUTION: A rack has the integral rectangular structure connected with a vertical support shaft. A circular groove is formed on the surface of the rack with the same shape as agricultural products including watermelons and other fruits. Plural protrusions are arranged in circular or polygonal form with regular distances on the inner surface of the groove. Each protrusion has the size and thickness corresponding to the kinds of the agricultural products. Preferably, two and more protrusions are formed depending on the usage and kinds of the agricultural products. The groove has specific depth for keeping the agricultural products at the depth of 1/3 or 1/2 of the diameter of the products. A hole is formed in the center of the bottom of the groove, and a rectangular groove is formed on the surface of the groove to hold the support shaft. The groove holding the vertical support shaft is depressed slightly into the upper and the lower surface of the rack. Therefore, the agricultural products including watermelons and other fruits are kept on the rack without damage.
