PURPOSE:To facilitate attachment and detachment of boards each other and to increase an effectively available space. CONSTITUTION:Protrusions 5 having heads 5a are provided at both sides of a male connector 3 mounted on a lower board 1. On the other hand, holes 6 are respectively formed at positions opposed to the heads 5a at both sides of a female connector 4 mounted on an upper board 2. A diameter of each hole 6 is smaller than the size of the head 5a, and the head 5a can be detachably connected to the hole by elastically deforming the head 5a. Thus, attaching and detaching operations of the boards 1, 2 can be facilitated without using a tool. A reduction in effectively available spaces of the boars 1, 2 can be decreased as compared with the case for holding by a conventional spacer. As a result, the effectively available spaces are increased. |
