PROBLEM TO BE SOLVED: To adjust the operating position of a ball shooting handle matched with the posture of a player himself/herself or the like in a vertical pachinko game machine. SOLUTION: To an outer cylinder 31 extended forwards from the front surface of a front frame 4, an inner cylinder 32 holding the ball shooting handle 34 is freely slidably inserted. A locking screw 71 screwed to the side face of the outer cylinder 31 is fitted to one of a plurality of locking holes 72 provided on the side face of the inner cylinder 32, and the inner cylinder 32 is fixed to the outer cylinder 31. A spring force varying mechanism varying the spring force of a return spring 45 energizing a ball shooting rod 42 in a shooting direction is constituted of a shaft member 60 transmitting the twist operation of the handle 34 and a spring operation mechanism receiving the twist operation of the shaft member 60 and varying the spring force of the spring 45. Further, the shaft member 60 is constituted of a driving side shaft member 61 connected to the handle 34 and a driven side shaft member 62 transmitting the twist operation of the driving side shaft member 61 to the spring operation mechanism while allowing the slide movement in back and forth directions of the driving side shaft member 61.
