PROBLEM TO BE SOLVED: To increase the interesting property of the movement of a game ball in a frame member (center accessory or the like) of a variable display device. SOLUTION: The game balls B which enter a top ball entrance 60 pass through a ball entrance 31, a left warp gutter and a right warp gutter, are guided to a first ball free movement surface (first ball free movement surface rear surface 35, first ball free movement surface front surface 42), freely move on the first ball free movement surface, and fall down directly, or further fall down to a left third ball free movement surface 80 or a right third ball free movement surface 81, freely move and then fall down. In the meantime, the game balls C which enter a left ball entrance 61a and a right ball entrance 61b pass through a left ball passing hole 51a, a right ball passing hole 51b, a left warp gutter 41a and a right warp gutter 41b, freely move on a second ball free movement surface 43 and then fall down from a ball exit 52.
