PROBLEM TO BE SOLVED: To provide equipment for a game ball, which maintains a role as a flow passage for the ball even if breakage or the like of the flow passage for the ball occurs in unpredictable timing, and wherein cost does not pile up even if performing the replacement of a breakage part of the flow passage for the ball caused by the breakage or the like.SOLUTION: This equipment 1 for the game ball configures a flow passage formation member for the ball connecting a high position carrying path and a lower island tank inside a game machine island, and includes unit flow passage formation members 2, and cover members 3. The unit flow passage formation member 2 is inserted into the cover member 3 to form a double-structure unit composite body 5. The thus formed double-structure unit composite bodies 5 are connected in series to form a carrying flow passage flexible between the unit composite bodies 5. |
