<p><P>PROBLEM TO BE SOLVED: To provide a Pachinko machine capable of preventing malfunction of an attacker device caused by jumping of game balls. <P>SOLUTION: A restraining plate 31b is raised to extend toward an out hole 29 on the back side of a sliding surface of a lower guide rail 11 defining a lower portion of a play area 12 on a game board 3. The thickness of the restraining plate 31b is the maximum at the center, gradually thinning toward outside. The center of the restraining plate 31b is made to planarly overlap with the rear of a guide surface 11a formed at the lowermost position of the lower guide rail 11, so that the rear of the guide surface 11a with the largest level difference among wedge-shaped level differences formed in the boundary between the sliding surface and the guide surface 11a of the lower guide rail 11 is covered by the center of the restraining plate 31b from above. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
