When a part of the recess for positioning projects and is formed on the back face of the game board over the outside of a fixed position of the hem part of the plate back cover, a part of the boss is allowed to project to the outside of the bottom face of the hem part for fitting into the recess for positioning. <P>COPYRIGHT: (C)2012,JPO&INPIT |
