Two receiving tubes 35 are connected to an inside of the upright frame and a rod 29 on a leading end of the fabric 21 is engaged.
 Referring to FIGS. 2 and 3, the U-shaped frame 34 can be detached from the sleeves 31 and the two side rails 41 are folded toward the board 1 so that the board 1 together with the two side rails 41 can be inserted in the space 32 between the upright frame 30 and the U-shaped frame 33. The detached U-shaped frame 34 is supported on the hooks on the back of the board 1 Referring to FIG. 6, the fabric 21 has two zipper members 23 as shown in FIG. 4 and can be engaged with the zipper members 43 on the two side fabrics 42. The fabric 21 and the side fabrics 42 are then define a U-shaped space in which balls can be kept therein so that the players need not to purchase the balls all the time.
FIG. 7 shows that the board 1 may also be movably connected to two rails 50 on a wall and the height of the board 1 can be adjusted by a push-button switch.
