PROBLEM TO BE SOLVED: To simplify a power transmission mechanism. SOLUTION: A design face part 24 is provided in a tip of a first movable body 21 rotatably attached by a first movable shaft 23 in an interior of a variable prize-winning component 1. The first movable body 21 is pendulously moved by rotation of a first movable driving source 17 and a mechanical power transmission mechanism comprising an arm 16, a protrusion 20 and an oblong hole 22. A second movable body 25 is rotatably provided in an interior of the design face part 24. By attracting and releasing a magnetic body 29 provided on the second movable body 25 by excitation and demagnetization of an electromagnet 32 attached to an attaching part 31 provided on the first movable body 21, a ball delivery body 28 of the second movable body 25 is vertically moved in front of the design face part 24.
