PROBLEM TO BE SOLVED: To protect a tray by reducing shock applied to a bottom of a pachinko ball receiving tray in dropping pachinko balls to the tray, and restrict generation of shock noise generated at the bottom of the tray at the time. SOLUTION: A shock absorbing sheet or cushion sheet of a thickness of about 3-5mm is cut in almost similar sizes to those of a bottom surface of a housing box 11 of a pachinko ball receiving tray to form a sheet, an adhesive film is applied to a lower surface of it, and it is put into the housing box 11 to roughly cover the whole surface of the box 11. |
