PROBLEM TO BE SOLVED: To achieve stable swinging motion of movable members of a movable accessory device. SOLUTION: A game machine has the movable accessory device 65 provided on a game board. The movable accessory device 65 has a core member 87 which can move relative to a base body 86 along the axis thereof, a plurality of the movable members 88 which are arranged so as to surround the core member 87 and to swing as the core member 87 moves, and a resilient member 98 which is pressed by the movable members 88 when the movable members 88 swing so as to separate from the core member 87. When the core member 87 moves in one direction, each movable member 88 swings so as to separate from the core member 87 using a swing shaft 88a as a fulcrum against an urging force of the resilient member 98 because a pressure receiving part 88b receives the thrust generated by movement of the core member 87. When the core member 87 moves in the other direction, the movable member 88 swings so as to approach the core member 87 using the swing shaft 88a as the fulcrum by the urging force of the resilient member 98.
