<P>PROBLEM TO BE SOLVED: To provide a game board made of a synthetic resin which is configured to be piled up on another one without being damaged or collapsing the pile in a production process. <P>SOLUTION: A game board body 1 made of a synthetic resin is molded into a plate shape by injection molding so that a playfield 2 has a predetermined thickness and a flat surface, a large number of game pins 14 are fixedly planted in the surface of the playfield of the game board body, and the guide rail 13 is mounted to surround the playfield. Projecting column bodies 11 having a predetermined projection height is formed on the back side of the game board body corresponding to the back side of the guide rail, and a frame-shaped outer edge rib 8 projecting to a height equal to or higher than the projecting column body is integrally formed on the back side of the outer peripheral edge of the game board body. When the game board bodies are piled up on each other, the outer edge rib of the upper game board body abuts on the surface of the outer peripheral edge of the lower game board body, and the playfield of the lower game board body and the playfield of the upper game board are separated from each other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
