PROBLEM TO BE SOLVED: To provide a self-batting training apparatus of ping-pong installable on a desk of an office and a ping-pong table, capable of simultaneously housing a rebounding unit, a racket, and a ping-pong ball, and carriable and utilizable anytime and anywhere. SOLUTION: Two rebounding plates (acrylic plates) 1 and 2 are juxtaposed in a folding screen shape. Support tubes 9 are adhered in two places on the inscribing side. A support bolt 4 is inserted inside as a hinge type, and is formed as an openable-closable structure. The rebounding plates 1 and 2 are integrated with the support bolt 4 by a blind cap 6, a support nut (a flat nut) 7, and a butterfly nut 8, and the height is determined by the flat nut 7. Opening-closing of the rebounding plates 1 and 2 is positioned by fastening of the butterfly nut 8. The support tubes 9 are also adhered to an outside surface of the rebounding plates 1 and 2, support bolts 3 and 5 are inserted, and the rebounding plates are formed as a structure supportable at three points by the three support bolts 3, 4, and 5. Cushion plates 11 are stuck to a surface of the rebounding plate 2 to optimize a rebounding angle.
