PROBLEM TO BE SOLVED: To make a plurality of pieces perform interesting actions at the same time by hauling and moving the pieces on mutually linked units by rotating and driving any one of driving dials to be engaged in the case of cooperation in the direction of side. SOLUTION: A standard unit type is provided with a frame base 1 having a top plate 6 on the upper surface and opening side parts, a driving dial 10 freely rotatably supported inside the frame base 1 while being partially exposed from the opening of this frame base 1 and having engage teeth 11 to be mutually engaged with the frame base 1 in the case of adjacent location, a cooperating means 20 for mutually adjacently cooperating the frame base 1 and pieces 30 set on the top plate 6 so as to be hauled and moved by operating the magnetic force of a permanent magnet 12 located on the driving dial 10. In a driving unit type,. The driving dial 10 is driven by a motive force source 40 located on the top plate 6. The units are mutually cooperated in the direction of side and all the driving dials 10 are driven and rotated by the driving power of the motive force source 40 or manually so that a plurality of pieces 30 on the top plate 6 can be simultaneously moved.
