<p>PROBLEM TO BE SOLVED: To provide a tank rail, even when a substantial gradient cannot be secured for the tank rail, capable of reliably preventing ball clogging.SOLUTION: A tank rail 20 includes two alignment paths 25, and each alignment path 25 includes a catch regulation part consisting of a second step part 27B at a boundary part between an upstream-side protruding strip 26U and a downstream-side protruding strip 26L, and a guide protrusion 32 provided on a ceiling board 30. When a Pachinko ball group vertically stacked into a lump reaches the second step part 27B, the guide protrusion 32 comes into contact with upper-side Pachinko balls to pass the lower-side Pachinko balls preferentially, and then makes the upper-side Pachinko balls to enter behind the preceding Pachinko balls. This configuration can break the lumped Pachinko balls to prevent the Pachinko ball from being caught by the tank rail 20, thereby preventing ball clogging.</p> |
