Since the front plate 15a of the guard member 15 is disposed in the gap W1 with the glass plate 4b, it is possible to prevent the hit ball 30 from being caught in the gap W1 when the opening / closing shutter 14 is opened. . Therefore, since the opening / closing shutter 14 is prevented from being opened due to the hit ball 30 being caught in the gap W1, it is possible to prevent great damage to the game hall. Further, since the hitting ball 30 is prevented from passing through the gap W1 by the front plate 15a of the guard member 15, the hitting ball 30 can be awarded to the opening 13a of the big winning opening with the opening / closing shutter 14 opened. It is possible to prevent the player from feeling dissatisfied or uncomfortable.

  In addition, the amusement hall must attach the glass plates 4a and 4b having the thickness specified by the manufacturer of the pachinko gaming machine 1 to the glass door frame 4, but the thickness is different from the specified thickness, for example, the specified The glass door frame 4 may be attached to a glass plate thinner than the thickness or a glass door frame 4 thicker than a specified thickness. In such a case, the gap between the front end portion of the door member 14a of the open / close shutter 14 (left side in FIG. 4) and the glass plate attached to the glass door frame 4 varies, but according to the variable prize apparatus 12 of this embodiment. In this case, since the front plate 15a of the guard member 15 is disposed in the gap, it is possible to prevent the hitting ball 30 from being caught in the gap when the opening / closing shutter 14 is opened, and the gap is used for hitting the gap. 30 can be prevented from passing.

  Since the guard member 15 is made of a synthetic resin material such as a polycarbonate resin having a transparent impact resistance, even if the hit ball 30 (see FIG. 4) that has dropped in the game area 8 collides, the guard member 15 It is possible to prevent chipping and breakage. In addition, since the hitting ball 30 winning in the opening 13a of the big winning opening provided behind the guard member 15 can be visually recognized, it is possible to improve the interest of the player. Furthermore, the guard member 15 also has a role as a decorative member of the variable winning device 12, and can improve the interest of the player.
