PROBLEM TO BE SOLVED: To provide an opening and closing/attachment and detachment mechanism of a game board which facilitates the attachment and detachment operation of the game board. SOLUTION: This opening and closing/attachment and detachment mechanism includes: a fixed hinge member 112 arranged in a housing frame 10 for housing a game board; an oscillation hinge member which is arranged on the game board 20 and can relatively swing in an engaged and unengaged state with a hinge pin 112c of the fixed hinge member; and a press member 140 which includes a press side member 144 in the housing frame 10 projecting toward inside of the frame and is capable of being elastically deformed in the back and forth direction. When the oscillation hinge member is engaged with the fixed hinge member, the press side member 144 is engaged with a front face of the game board 20 and biases the game board 20 backward.
