PROBLEM TO BE SOLVED: To provide a tank rail capable of surely preventing ball clogging even if a sufficient space cannot be obtained. SOLUTION: A tank rail 20 includes two alignment paths 25, and its bottom wall 21 has the first stepped part 27A as a reserve stepped part, and furthermore, one upstream projection 26U on an upstream side and two downstream projections 26L on a downstream side via the second stepped part 27B. Pachinko balls fallen in the second stepped part 27B are received by the downstream projections 26L. Here, while the upstream projection 26U supports the lowest point of a Pachinko ball, the downstream projection 26L supports a point higher than the lowest point of the Pachinko ball, so that a head drop of the Pachinko ball when falling in the second stepped part 27B can be increased compared with that supporting the lowest part of the Pachinko ball in both cases before and after the falling. This constitution can increase a shock to Pachinko balls passing the second stepped part 27B or easily crush the structure of a lumped Pachinko ball mass so as to effectively prevent the ball clogging.
