SOLUTION: A plurality of riblike impact diffusion pieces 15 extending in parallel with the underside of the ball tray 5 are provided in the underside at appropriate intervals. The riblike impact diffusion pieces 15 make the nominal frequency of the bottom wall 9 of the ball tray 5 nonspecific and restraining of game balls from rebounding. COPYRIGHT: (C)2007,JPO&INPIT
