PROBLEM TO BE SOLVED: To enhance interest by increasing variations in an emission performance.SOLUTION: A movable performance device M1 includes a first movable body unit U1 and a second movable body unit U2 that are arranged side by side. The first movable body unit U1 includes a first movable body 40 and a second movable body 41 that are movable between an initial position and a movement position separated from the initial position by different travel distances. The second movable body unit U2 includes a third movable body 140 and a fourth movable body 141 that are movable between the initial position and the movement position separated from the initial position by different travel distances. The first movable body 40 and the second movable body 41 include first, second line emission parts 96, 120 overlapping in front and in rear in relative displacement in a vertical direction of the movable bodies 40, 41. The third movable body 140 and the fourth movable body 141 include third and fourth line emission parts 156, 176 overlapping in front and in rear in relative displacement in a vertical direction of the movable bodies 140, 141. |
