PROBLEM TO BE SOLVED: To absorb an error in manufacture when assembling a retaining frame using extruded materials. SOLUTION: This retaining frame 20 for retaining a Pachinko machine in island equipment of a game parlor is assembled using frame constructional elements constituting the four sides. For example, when connecting a frame constructional element 25 and a frame constructional element 28 using two connecting plates 35 and 36, the frame constructional elements 25 and 28 are clamped into a non-contact state from each other by the connecting plates 35 and 36 and fixed with screws 55. For example, even if the positions of through-holes 40 and 41 provided in the frame constructional element 25 are deviated or the positions of through-holes provided in the frame construction element 28 are deviated, this constitution can thus assemble the retaining frame 20.
