PROBLEM TO BE SOLVED: To provide a game machine frame which eliminates warpage of a game board. SOLUTION: In a process of mounting the game board 41 on a movable frame 3 and thereafter closing a front door 4 and a tray structure body to be supported by the the movable door 3 so as not to be opened and closed, a board pressurization protrusion 32 faces the front surface of a left/upper corner part 55 positioned more at a left/upper part than an outer guide rail 44 at the game board 41. When the warpage of the game board 41 is caused and the left/upper corner part 55 around the ball exit of the ball shooting path of the game board 41 projects to a front side, the board pressurization protrusion 32 pushes and moves the left/upper corner part 55 from the front side to a back side to keep the dimension between a transparent panel 30 and the front surface of the game board 41 to be a regulated dimension. When the board pressurization protrusion 32 is provided at a hinge bracket 33, rigidity when the board pressurization protrusion 32 pushes the left/upper corner part 55 of the game board 41 from the front side to the back side becomes stronger.
