PROBLEM TO BE SOLVED: To provide a shooting angle adjusting mechanism which can realize the uniform flight of the balls regardless of variations or the like in the component parts of the game ball shooter. SOLUTION: A guide member 110 provided with an auxiliary rail 113 for guiding the game balls moving toward a guide rail 33 from a shooting rail 23, a support member to inclinably support the guide member 110 and an inclination angle setting structure 130 which enables the stepwise adjustment and setting of the inclination angle of the auxiliary rail part 113 relative to the direction in which the shooting rail 23 extends by retaining and holding the guide member 110 supported on the support member at any angle position of a plurality of preset angle of inclination positions are built in the lower area of the front frame positioned below the game board. Thus, a shooting angle adjusting mechanism 100 is able to stepwise adjust a plurality of angles, at which the game balls are shot to the guide rail 33 from the game ball shooter, in multiple steps by setting the inclination angle of the auxiliary rail part with the inclination angle setting structure 130.
