PROBLEM TO BE SOLVED: To provide a front frame opening/closing support structure of a pachinko machine capable of keeping an open state without letting a front frame fall even when unintended external force is applied and a hinge shaft is detached from the inside of a hinge hole. SOLUTION: In the structure of inserting the hinge shaft 67 provided on the hinge plate surface of an inner frame to the hinge hole 74e through a notched part 74f formed on the hinge plate part 74d of the front frame 20, making the front frame 20 freely openable and closable and also attachable and detachable to/from the inner frame by closing the hinge hole and the notched part, and opening and closing the hinge hole and the notched part by moving a back-and-forth movement shaft part 80a back and forth by the operation shaft part of an operation rod 80, a hinge shaft stopper 101 is attached to the upper surface of an upper hinge substrate part 74c positioned on the lower surface side of an upper hinge plate part 74d. For the hinge shaft stopper 101, on the total of three sides which are two sides 107 and 108 facing each other at an interval along the inserting and detaching direction of the hinge shaft 67 to/from the hinge hole 74e and a front side 109 connecting both ends on the opposite side of the hinge hole 74e of the two sides, a wall part 103 for blocking the getting-over and detachment of the hinge shaft 67 which is detached from the hinge hole 74e to the side part is provided.
