PROBLEM TO BE SOLVED: To provide a tank rail of a pachinko machine resisting jamming of balls. SOLUTION: The downgrade angleθ1 of a first inclined passage 37 where game balls P flowing out of the exit 21 of a ball tank 20 first drop is greater than the downgrade angleθ2 of a second inclined passage 40, so that the initial speed of the game ball P at its drop point when the game ball P coming out of the exit 21 drops onto the second inclined passage 40 can be made higher than the initial speed of the game ball at its drop point when it is assumed to drop onto an inclined passage with the same downgrade angle as the downgrade angleθ2 of the second inclined passage 40. Thus, even if the number of game balls P coming out of the exit 21 increases, the number of game balls P which flow down can follow this increase, preventing the jamming of the game balls P at the drop point.
