PROBLEM TO BE SOLVED: To hide the rear mechanism of an electric component which is provided on a plate-shaped structure made of a light-transmissive synthetic resin. SOLUTION: A component side fitting leg 39 of a start winning component 24 is inserted in a through hole 34 of the plate-shaped structure 4, and a protuberance 58 of a shielding side fitting leg 56 of a shielding body 35 is inserted in the through hole 34 of the plate-shaped structure 4. Then, the barrel 62 of a set screw 61 is inserted in a screw fitting hole 40 through a head housing section 59 and a screw insertion hole 60 from the rear side of the shielding body 35, and is fastened to the component side fitting leg 39. The head section 63 of the set screw 61 comes into contact with the rear surface around the screw insertion hole 60 on the front wall of the head housing section 59. When the start winning part 24 and the shielding body 35 are fitted on the plate-shaped structure 4 with the set screw 61 under a state wherein the plate-shaped structure 4 is sandwiched from the front and the rear, rear mechanisms such as a driving mechanism which protrudes to the rear side from the plate-shaped structure 4, a start winning ball detector, a detector engaging section, and a ball exit section and so forth in the start winning component 24 are hidden from the front side of a game board 1 by the shielding body 35.
