PROBLEM TO BE SOLVED: To prevent a ball from being clamped among a projection, the edge part of a ball entrance, and an opening/closing body when the opening/closing body closes. SOLUTION: In a lower variable prize winning component 15 which has a ball entrance 22, an opening/closing body 23 for opening/closing the ball entrance 22, and a projection 25 placed on right and left sides of the opening/closing body 23, the ball P passes a gap between right adjustment nails 34 and 35 to become a ball P1 shown by a dashed-dotted line as shown by an arrow X1, the ball P1 is discharged from the projection 25 on the left side in a way that it advances toward the projection 25 on the right side from the upper surface of the projection 25 on the right side as shown by an arrow X2 to become a ball P2 shown by a virtual chain line, the ball P2 collides against the lower side of a right obstacle member 28 as shown by an arrow X3, and has its direction changed downward, and the ball P2 does not reach the projection 25 on the left side but advances toward the ball entrance 22. Thus, when the ball P2 bounced downward by the right obstacle member 28 reaches the ball entrance 22 and even when the opening/closing body 43 is changed from an opened state to a closed state, the ball P2 is not clamped among the projection 25 on the left side, a front plate 21 in the peripheral edge part of the ball entrance, and the opening/closing body 23.
