PURPOSE:To provide a housing and a manufacturing method thereof in which the number of manual working steps is minimized in order to facilitate automation of manufacturing process. CONSTITUTION:The struts 11c, 11d, 12c, 12d are screwed to reinforcing members 13a-13d with the head of bolt projecting to the inside of a framework 1 to construct the rectangular bottom face thereof and the struts 11a, 11b, 12a, 12b are similarly constructed, by means of reinforcing members 13e-13h, into a rectangular upper face of the framework 1. The struts 10a-10d are similarly screwed to the bottom and upper faces of the framework 1 thus forming a box as a whole. The reinforcing members 13a-13h hold the struts to intersect perpendicularly in the longitudinal direction at the end parts thereof. |
