PROBLEM TO BE SOLVED: To simultaneously close the lower side and upper side of a pair of left and right opening/closing members, in a game machine adopting a structure of driving by applying driving force to either one of the upper side and lower side of the pair of left and right opening/closing members. SOLUTION: Left and right heart-shaped opening/closing members 30L and 30R are provided in the state of being slidable to the left and right by rails 141 and 142 by an upper and lower metal rods. The left and right heart-shaped opening/closing members 30L and 30R have contact surfaces 98L, 98R, 99L, and 99R to be in contact with each other in a closed state on the upper side and lower side of the end surface on the closing side, and are inclined at an angleθand arranged so that the contact surfaces 98L and 98R on the upper side to be the side to which the driving force is not pplied are shifted in a closing direction from the contact surfaces on the lower side to be the side to which the driving force is applied in the state of being stopped without being brought into contact with each other.
