PROBLEM TO BE SOLVED: To exchange game instruments with different shapes and control heights of the same instruments easily by installing a body frame which supports a mounting frame that holds the game instruments and providing a position control mechanism which arranges the mounting frame at a position of stated height of the body frame and supports the mounting frame. SOLUTION: A mounting frame 10 which holds game instruments G, i.e., a pachinko stand and a video game machine and so forth is installed at a position of a stated height of a body frame 1 that is fixed on a floor with a position control mechanism. The position control mechanism is constituted by being provided upper and lower parts of position control parts 4 and 5; 6 and 7 which are provided at a side of the body frame 1 and upper and lower parts of mounting parts 15 and 16; 17 and 18 which are provided at a side of the mounting frame 10. The mounting frame 10 is fixed at an appropriate position of height by screwing and cramping a nut by dint of coinciding with plural position control openings which are formed at each position control parts 4-8 toward upper and lower directions respectively at irregular intervals with mounting openings which are formed at the mounting parts 15-18 appropriately and inserting a volte as a fitting means into the coinciding openings.
