PROBLEM TO BE SOLVED: To provide a phantasmagoric configuration which shows that balls are caught or rebounded. SOLUTION: A rotary guiding element 30 rotates in the directions indicated by arrows X1 and X2 from Fig.(a), and an elastic piece 46 comes into contact with an obstacle protrusion 33 as shown in Fig.(b) from the lower side, and warps in a manner to draw an arc which protrudes upward as the whole. The rotary guiding element 30 rotates in the directions indicated by arrows X1 and X2 from Fig.(b), and the elastic piece 46 passes through the obstacle protrusion 33 from the lower side to the upper side as shown in Fig.(c), and is arranged between the obstacle protrusion 33 and a guiding protrusion 34 by being linearly restored at a diagonally upper side as the whole. The rotary guiding element 30 reverses in the directions indicated by arrows X3 and X4 from Fig.(c), and the elastic piece 46 comes into contact with the obstacle protrusion 33 from the upper side as shown in Fig.(d), and warps in a manner to draw an arc which protrudes downward as the whole.
