PROBLEM TO BE SOLVED: To provide a game machine which can prevent falling of the balls from the game ball leading-out gutter part at the time of the opening of the front frame door. SOLUTION: The game machine has a seesaw member 53 pivoted on a game ball leading-out gutter part 40 formed together with a retreat area 47 tilted downward sidewards of a communicating area 46 when the front frame door 6 is opened, and an energizing means for energizing the seesaw member 53 to turn to open the upper stream area of retreat area 47 and position it in a position for shutting off the lower stream area, a return action member 58 for causing the seesaw member 53 to turn and return against the energizing force of the energizing means to open the lower stream area of retreat area 47 and position it in the position for shutting off the upper stream area when the front frame door 6 is closed. By this structure, a game ball in the communicating area 46 flows in to retreat area 47 when the front frame door 6 is opened, and the game ball flowing in to retreat area 47 is discharged when front frame door 6 is closed, and the balls can be surely prevented from dropping out of the game ball leading-out gutter part 40 when the front frame door 6 is opened.
