<P>PROBLEM TO BE SOLVED: To provide a movable performance device in which unevenness in movement in the opposite direction to each other of a pair of movable decoration means is eliminated by devising to elastically absorb backlash likely to occur in a mesh structure interposed between the pair of movable decoration means and a driving source. <P>SOLUTION: Right and left both-side mesh mechanisms 242, 243 move right and left both-side racks 242b, 243c in the opposite direction to each other in accordance with clockwise/anticlockwise rotation of a stepping motor under mesh between the mechanisms and a pinion 241a supported by the stepping motor to move the right and left both side movable decoration members in the opposite direction to each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
