To simultaneously secure a housing capacity while securing a required piping space with simple structure concerning a furniture equipment having a housing rack.

The depth of a top plate 7 is reduced to a size after securing the piping space like a bottom plate 8, and the housing rack 10 with a cover having the same upper face as that of the top plate 7 is installed within the piping space. Consequently, by utilizing the housing rack 10 while securing the required piping space, the reduction of housing volume is minimized and a cabinet structure can be simplified, thereby standardizing and sharing of parts are not hindered.
