PROBLEM TO BE SOLVED: To provide a storage tank of a Pachinko island stand for allowing a Pachinko ball to smoothly flow without staying on the periphery of a ball extracting port, and causing no damage of a ball extracting opening. SOLUTION: This storage tank 12 is provided with a ball extracting device 20 for penetratingly forming the ball extracting opening 15 in a wall plate 14 for making the Pachinko ball stored in a storage space flow outside, and having a shielding member 22 movable to a position for blocking up the ball extracting opening 15 and an opening position. When the shielding member 22 exists in the blocking-up position, an inside surface of the shielding member 22 becomes the almost same plane as an inside surface of the wall plate 14, and the shielding member 22 exists in the position for blocking up the ball extracting opening 15, and since the inside surface of the shielding member 22 becomes the almost same plane as the inside surface of the wall plate 14 in an ordinary state of extracting no Pachinko ball in the storage tank 12, the pachinko ball smoothly flows without staying on the periphery of the ball extracting opening 15 in the storage space.
