PROBLEM TO BE SOLVED: To provide a game machine allowing an operator to attach a guide rail in the stable state to an appropriate position in a shot ball guide path for guiding shot balls onto a play area of a game board without requiring special skill. SOLUTION: An adjusting fixing member 12 is rotatably journaled to a guide rail adjusting fixing part 98 of a guide rail attaching unit 9 for fixing and holding the upper end of the guide rail 10 at a fixed position, and the lower end of the guide rail 10 is fixed with a rail end fixing part 12b of the adjusting fixing member 12. When the rail end fixing part 12b is displaced as the adjusting fixing member 12 is rotated in the direction C of adjustment, the whole guide rail 10 is compressed while the lower end is moved in the direction of narrowing the width of the shot ball guide path 7b. As a result, the pressure onto the opposite side acts on a region above the lower end of the guide rail 10, and the region is effectively pressed on the inner face of an outside wall part. In this way, the state of strain of the guide rail 10 can be adjusted without distorting the guide rail 10. COPYRIGHT: (C)2008,JPO&INPIT
