PROBLEM TO BE SOLVED: To rationalize assembling by simplifying the relative positioning a shooting rail and a shooting rod. SOLUTION: The upper half of a front frame 5 can be opened and closed by a glass frame 2 and the lower half of the front frame 5 can be opened and closed by a closing panel 3. The closing panel 3 is opened to enable a shooting unit 14 to be attached and removed from the front side, with the mounting base member 26 of the shooting unit 14 anchored to an upstanding face 13 at the free end of the closing panel 3. A recess 27 for fitting the mounting base member 26 of the shooting unit 14 therein is formed in the upstanding face 13. With the mounting base member 26 fitted in the recess 27, an inlet of a ball guide passage 16 on a game board 8 is located ahead of the inclined upper end of the shooting rail 33 of the shooting unit 14.
