PROBLEM TO BE SOLVED: To facilitate attaching work of a guide rail to a game base board. SOLUTION: As one end of a belt-like outer guide rail 3 made of metal such as stainless steel is inserted into a guide groove 40 from the front lower part of the game base board 2 and moved upward, the one end of the outer guide rail 3 is moved in a rail insertion groove 19 from a rail abutting part 22 in the direction toward a rail abutting part 23 and is taken in a rail receiving groove 45. After that, the other end of the outer guide rail 3 is disposed on the upper side of the rail abutting part 22 from the guide groove 40, so that the outer guide rail 3 is inserted into the rail insertion groove 19 to be shaped in the upper projecting arch. Ends of the outer guide rail 3 are held between the rail abutting parts 22 and 23, and the outer guide rail 3 is supported from outside by a belt-like rail support body 20 provided along the outer edge of the rail insertion groove 19. In this way, the outer guide rail 3 is inserted into the rail insertion groove 19 to be attached to the game base board 2. COPYRIGHT: (C)2008,JPO&INPIT
