PROBLEM TO BE SOLVED: To provide a ball gutter device for a game machine capable of dissolving ball biting by imparting force for pushing back the ball of an upper stage among the balls overlapping up and down and flowing down in a vertical direction from one end side of a horizontal gutter to a ball break-down member provided in a middle part between one end side and the other end side inside the horizontal gutter. SOLUTION: The ball gutter device for the game machine is provided with the horizontal gutter 2 attached on the back surface of a game machine frame for making the balls flow down from one end side to the other end side and a ball break-down member 3 provided in the middle part between one end side and the other end side inside the horizontal gutter. A gap smaller than a diameter of two balls and larger than a diameter of one ball is formed between the ball break-down member and the bottom part of the horizontal gutter, the ball break-down member is connected to an elastic bar-shaped support body 7, and a part projected to the outer side more than the ball break-down member of the support body is connected to the horizontal gutter. As the ball break-down member moves in a ball flow-down direction with the support body as a center by the ball of the upper stage overlapping up and down from a bottom part from one end side to the other end side in the horizontal gutter, the support body is formed as a torsion bar which generates torsion whose center is the center of the support body.
