PROBLEM TO BE SOLVED: To provide a structure which impedes the illegal opening/closing of a control board storage box for storing a control board, to prevent the illegal use of the control board provided at the back face of a Pachinko game machine body or the back face of a game board. SOLUTION: An insert pin with head is inserted toward an insert-through fitting hole 228 of an insert pin fixing base 210 mounted to a case member 204, from a pinhole of an insert pin insertion part 208 of a cover member 202, and a groove part 250 of the insert pin with head is undetachably locked by a locking piece of the insert-through fitting hole 228. A spring 246 is previously inserted through the insert pin in advance, and the cover member 202 and the case member 204 are fixed without shakiness by the energizing force of the spring 246.
