Abstract
A housing structure of an electric appliance has an upper case and a lower case. The upper case is provided with a plurality of logic holding portions arranged on inner sides of left and right side face portions of the upper case. An interior one of the logic holding portions has a protrusion engagement portion which is defined by a slant face and a front face of the interior holding portion. The lower case is provided with a lower case side engagement portion which engages releasibly with the protrusion engagement portion. The lower case side engagement portion has a resilient half portion in a half support which is formed on a bottom face of the lower case and on which an extrusion portion that engages releasibly with the protrusion engagement portion and a threaded hole for a screw are formed. The housing structure is disassembled by screwing the screw into the threaded hole so that the screw's end portion contacts slidably with the slant face of the interior logic holding portion so as to move the resilient half portion downwardly away from the upper case to thereby release the engagement of the extrusion portion from the protrusion portion.
