PROBLEM TO BE SOLVED: To easily perform installation inside a pachinko island base. SOLUTION: This unit recovery gutter 1 comprises: a ball path 3 with a plurality of grooves 12 to be the path of pachinko balls, formed by arranging plates 11 side by side in a duckboard shape at an interval smaller than the diameter of the pachinko ball; and a ball path frame 2 provided with a pair of side plates 4 whose upper end is formed horizontally, a bottom plate 5 where a gradient for making the pachinko balls smoothly flow down is formed and a means which can be mounted on the pachinko island base 30. The unit recovery gutter 1 is formed by spreading the ball path 3 on the bottom plate 5 of the ball path frame 2, and is constituted so as to be easily mounted in the forming space of a recovery gutter 20 at the inner side lower part of the pachinko island base 30 where a plurality of pachinko game machines 16 are lined or the pachinko island base 30 where a ball return device 19 is installed. Thus, just by performing the extremely simple work of horizontally installing the upper surface of the unit recovery gutter, the accurate gradient for making the pachinko balls flow down is formed in the ball path of the unit recovery gutter.
