PROBLEM TO BE SOLVED: To avoid waste of material or the like, reduce manufacturing costs, hardly allow a transparent plate to be broken, and minimizing an injury or the like due to breakage, if breakage occurs as much as possible. SOLUTION: Two plates (a front transparent plate 34 and a back transparent plate 35) are provided on the front and back sides of a window hole 5 of a game machine body 1, respectively, and a game board 12 is provided on the back of the transparent plates 34 and 35. A front transparent plate 34 is made of a synthetic resin plate, and a periphery edge part 48 bent backward from the outer periphery of the front transparent plate 34 and a strip-shaped bulkhead 38 projecting backward from the front transparent plate 34 to surround a game area 22 of the game board 12 are integrally provided on the front transparent plate 34. The periphery edge part 48 and the back end of the bulkhead 38 are made to abut on the back transparent plate 35 so that the front transparent plate 34 and the back transparent plate 35 are held by an outside holder 36.
