The dimension between the guide grooves 41 and 41 is set so that pachinko balls flowing through the guide grooves 41 and 41 do not contact each other. As a result, pachinko balls that have flown down the 5th game board but could not win are collected and discharged from the out ball communication port 40 to the out ball port 21, but in front of the out ball communication port 40. Therefore, it flows smoothly through one of the guide grooves 41 without buffering each other. Therefore, there is almost no risk that the pachinko balls entering the out ball mouth 21 are pressed against each other to cause the ball biting, and the ball is clogged near the out ball mouth 21.

Further, in a state where the inner guide rail 31 is laid on the game board 5 surface, as shown in FIG. 6, the one side edge 39 a of the decorative board member 39 is between the game board 5 surface and the rail plate part 27. It is interposed in the gap 42 to be molded and is sandwiched between the game board 5 and the rail plate portion 27. In this way, the one side edge 39a is sandwiched when the pachinko ball flowing down the surface of the game board 5 frequently collides with the guide rail main body 31a or the decorative board member 39 so that the fixing member 34 is slightly removed from the mounting hole 37. This is to prevent the inner guide rail 31 from rattling or loosening, so that this is prevented and the game is not hindered.

  Thus, the present invention is provided with the rail plate portion 27 formed integrally with the inner guide rail portion 26 on the upper surface together with the outer guide rail 25 on the inner frame 2 side. Therefore, it is possible to attach a part of the inner guide rail together with the outer guide rail 25, that is, the inner guide rail portion 26 to the inner frame 2 side. For example, when the game board 5 of the pachinko gaming machine P is replaced with an old one, Since the outer guide rail 25 and the inner guide rail portion 26 can be used as they are, the components can be used effectively and waste can be reduced. Further, even when the old game board 5 is separated, the outer guide rail 25 and the inner guide rail portion 26 are not provided, so that troublesome work in the separation process is reduced and the work efficiency is improved.

The inner frame 2a of FIG. 7, rail plate portion 43 is formed in the inner frame 2a and separate, yet, the rail plate portion 43 is exchanged freely disposed in a predetermined position of the inner frame 2a. That is, a plurality of bosses 44 having screw holes 44a are provided on the inner periphery of the opening window 4 of the inner frame 2a and in the lower right portion when viewed from the front side, and the rail plate portion 43 is positioned corresponding to the bosses 44. A screw insertion hole 45 is provided. An inner guide rail portion 26 is formed on the upper surface of the rail plate portion 43 in the same manner as described above.

  Then, with each screw insertion hole 45 corresponding to each boss 44, the screw 46 is screwed to each screw hole 44 a via each screw insertion hole 45, whereby the rail plate portion 43 is attached to the inner frame 2. To be attached. At this time, the rail plate portion 43 is also prepared with a different shape of the inner guide rail portion 26 so as to fit the board gauges of various game boards. FIG. 8 shows an example thereof, and the inner guide rail portion 47 is provided with a vertical surface portion 47a on one side of the upper surface and an inclined surface portion 47b that linearly inclines downward from the lower end portion thereof. . In the present invention, two types of rail plate portions 43 and 43a are shown. However, the shape is not limited to these shapes, and the inner guide rails 26 and 47 can be freely shaped so as to fit the board gauges of various game boards. You can prepare something that has changed.
