PROBLEM TO BE SOLVED: To provide a ball tray in which stable ball flow when the number of stored balls is small and the suppression of a ball pressure when the number of the stored balls increases, are made compatible and balls are discharged without obstructing the ball flow. SOLUTION: In the ball tray of a pinball game machine, a storage guide tray 56 capable of storing many game balls is provided and the game balls stored in the storage guide tray 56 are aligned and made to flow down. A game ball support surface is constituted of a first inclined support surface 56a on the downstream side and a second inclined support surface 56b on the upstream side which are both lowered to the downstream, the inclination angle of the second inclined support surface 56b is formed smaller than the inclination angle of the first inclined support surface 56a, a level difference 56d is provided on the connection part of both, and the second inclined support surface 56b is disposed so as to be higher than the first inclined support surface 56a. Also, on the downstream part of the second inclined support surface 56b, a ball discharge mechanism 70 capable of discharging the game balls stored on the upstream side by opening and closing a part of the second inclined support surface 56b is provided.
