PROBLEM TO BE SOLVED: To stabilize the guidance of a shot ball and prevent the occurrence of a disagreeable noise by mounting an outer rail for guiding the shot ball on a game board in such a state as inclined thereto. SOLUTION: An outer rail 11 is formed of an injection molded synthetic resin, and curved to the prescribed radius of curvature. The section of the outer rail 11 is formed to have an approximate L-shape made of a guide rail 12 and a mounting piece 13. In this case, the mounting piece 13 has a decorative shape and secured to a game board 1 via a screw hole 14. In addition, the guide rail 12 is made to have a slope at the prescribed angle ofαfor the surface of the game board 1 toward the center thereof, after being secured to the game board 1. Thus, an approximately V-shaped groove part 15 is formed between the guide rail 12 and the game board 1. Furthermore, a pachinko (Japanese pinball game) ball P is held on the groove part 15 and the travel thereof toward a glass panel G is thereby restricted. According to this construction, the ball P after shot is guided stably without any disagreeable noise.
