PROBLEM TO BE SOLVED: To continue a game while Pachinko balls are being pulled-out with keeping the ball pull-out port of the bottom of the ball tray of a Pachinko machine open. SOLUTION: The base 23 of a front tray part 21 of the ball tray 20 is provided with a ball extract port 28 disposed rather closer to a rear side inner wall surface 29 in the downstream of a communicating port 26. Thus, an opening area of the ball extract port 28 is secured so that when the ball extract performance in a large amount of stored balls is still secured and the amount of stored balls is decreased, the pachinko balls flowing into the front tray part 21 are moderately extracted from the ball extract port 28, and simultaneously the pachinko balls are enough supplied to a downstream part of the front tray part 21 from a passage between the front inner wall surface 32 and the ball extract port 28. A part of the front inner wall surface 32 opposite to the central part of the communicating port 26 is formed at an angle of inclination of 40 to 60 deg. to a front panel 19, whereby most of pachinko balls rebound from the front inner wall surface 32 are let flow down between the front inner wall surface 32 and the ball extract port 28 to be supplied to the downstream part.
