PROBLEM TO BE SOLVED: To provide a game machine frame unit which achieves a higher mounting accuracy of a ball guide unit arranged to be freely detachable. SOLUTION: The game machine frame unit includes: a supply path unit; the ball guide unit which is so arranged as to be detachably mounted on a base member; and a guide rib and a regulation rib which are arrayed on a straight line running vertically in substance. The first and second protruded parts 301e and 301f are installed on the outer circumference of the rotor 301 to prevent interference between the game balls passing through a plurality of guide paths 302 and 303, thereby enabling the smooth guidance of the game balls to a holding part.
