PROBLEM TO BE SOLVED: To provide a delivery device for a game ball, capable of surely pneumatically transporting the game ball to a target position by minimizing the influence of a wall of an air flow flowing in a ball delivery pipe on the game ball advancing from a ball supply pipe into the ball delivery pipe as much as possible to eliminate stoppage of the game ball within the ball supply pipe. SOLUTION: The ball supply pipe 14 is provided in the middle of the ball delivery pipe 13 for supplying the game ball A by air flow B in a branched state, and a ball take-out pipe 15 for guiding the ball A by air flow from the ball delivery pipe 13 is disposed on the top end side of the ball delivery pipe 13. The top end of the ball delivery pipe 13 is set in a position adjacent to a combining part of the ball supply pipe 14, and a decompression means 16 for the air flow B carried to the ball take-out pipe 15 from the ball delivery pipe 13 is provided between the top end of the ball delivery pipe 13 and the base end of the ball take-out pipe 15.
