ABSTRACT:
A spacer having an upper substrate at the center of which a coupling hole is formed, a lower substrate which is provided opposite to the upper substrate, and a plurality of support members bridging between the upper and the lower substrates so as to retain a space therebetween in which the mechanical strength against the loads applied in the horizontal direction as well as in the direction of twisting is extremely large, thus enabling the spacer according to the present invention to resist failure even if these large loads are applied thereto unlike the prior art spacers and thus obtaining a secured snap-fitting as well as thus making possibility of the spacer coming off from the wiring board difficult.
