PROBLEM TO BE SOLVED: To provide a pachinko game machine which realizes the saving of space on the rear of the playing body. SOLUTION: A guide shaft 46 vertical to the surface 60 of a rear mechanism board is provided and a flat surface 45 is formed about the axis of the guide shaft 46. The diameter of the shaft orthogonal to the flat surface 45 is determined as the minimum diameter r1 and the diameter of the shaft along the direction of the plane of the flat surface 45 as the base diameter r2. On the other hand, a guide groove 50 is made up of a ball levelling groove 51 with the width d1 enough to make the guide shaft 46 play about the axis within the groove and a ball stop groove part 52 with the width d2 almost equal to the minimum diameter r1. In such an arrangement, when the levelling of balls is executed, the guide shaft 46 is positioned within the ball levelling groove part 51. On the other hand, when the stopping of the balls is executed, the guide shaft 46 is inserted into the ball stop groove part 52 keeping it in contact with the top of the flat surface 45 so as to cross an upper groove rim 75 of the ball stop groove part 52.
