Here, the inner rail 72 faces the outer rail 71 provided at the left outer edge portion of the game board 20 and is an inner wall of the launching road surface 29 that guides the game ball launched from the ball launcher 50 to the game area. The barrier member 721 is attached via a small screw or the like along the launch road surface 29 side, that is, along the outer wall of the inner rail 72.

  The barrier member 721 is made of, for example, an elastic material such as hard synthetic resin, and is integrally formed with a bent portion 722 that is bent from the vicinity of the front end of the inner rail 72 to the outside (on the side of the outer rail 71 not shown) at about 45 degrees. .

  As shown in FIG. 6, when the glass frame 4 is closed to the front frame 3, the bent portion 722 of the barrier member 721 is elastically deformed to approximately 90 degrees and is in close contact with the back surface of the pair glass 410. Thereby, there is no gap between the front end of the inner rail 72 and the pair glass 410, and for example, a game area in which a gauge or the like is formed on the wire W inserted from between the glass frame 4 and the front frame 3 Can be prevented from entering.

  Furthermore, even if the glass frame 4 and the front frame 3 are pry open using a bar or the like, the bent portion 722 that is elastically deformed follows the pair glass 410 and is kept in a close contact state. No gap is generated between the front end of the glass and the paired glass 410. Therefore, it is possible to reliably prevent foreign objects from entering the game board 20 in which the game area is formed even for a hard fraud using such a bar.
