PROBLEM TO BE SOLVED: To easily enlarge the volume of a ball storing chamber by means of removing a partitioning plate, or the like, from the inner part of the ball storing chamber unless an ash tray is required by providing the ash tray which is divided by means of the freely attachable/detachable partitioning plate, or the like, inside the ball storing chamber arranged at the front surface side of a Pachinko (Japanese pinball game) machine. SOLUTION: A lower tray device 30 disposed in the lower edge part of a front frame 2 for attaching a game board is provided with a lower tray ball storing chamber 32 with an open top, which is more projected at the side of a front surface than a horizontally long lower tray base 31 which is fixedly attached to the front frame 2. The ash tray 40 is arranged inside the chamber 32 and, in this case, it is formed into divisions by the partitioning plate 41 which is inserted to the side part of the chamber 32 so as to be freely attachable/detachable. That is, the partitioning plate 41 is formed to be freely fitted from an upper part into vertical grooves 42 which are formed at the front wall part and the opposing rear wall part of the chamber 32 at a position where interference with a lower tray ball flow-in part 33 and a ball discharge hole part 34 is not cause. Then the partitioning plate 41 is drawn out so that the chamber 32 is made to be one space and the volume is enlarged.
