PROBLEM TO BE SOLVED: To easily and efficiently clean a collecting trough of a pachinko island. SOLUTION: The collecting trough 21 provided inside a support base 9 of the pachinko island 1 for collecting a pachinko ball discharged from a pachinko machine group 3 comprises a trough body 31 having a dust fall structure 35 in a bottom part, a reception trough 41 for receiving dust falling from the bottom part, and a trough support body 51 allowing individual detachment/ attachment of the trough body 31 and the reception trough 41 from/to the support base 9. Because the trough body 31 and the reception trough 41 can be individually detached from the support base 9, the stooping or squatting in the case of impossibility of the detachment is not required. Accordingly, work becomes easy, and efficiency is improved. COPYRIGHT: (C)2003,JPO
