PROBLEM TO BE SOLVED: To provide a knockdown housing case whose mutual respective members can be easily assembled and whose size can be reduced further while easily disassembling/separating them thereafter and a cost can also be reduced further. SOLUTION: Respective connecting parts 20 have a fitting part 22 and a fitting object part 23 which are formed in a vertically penetrating cylindrical shape and are partitioned by upper and lower parts of a step part 21, an elastic piece 24 formed in the fitting part 22 of these connecting parts 20, an engaging claw 25 arranged outside this elastic piece 24 and an engaging hole 26 which is formed in a part positioned just under the elastic piece 24 of the fitting object part 23 and with which a column 30 side engaging claw 35 is engaged. Then, a stopper 27 which projects inside the fitting object part 23 of the respective connecting parts 20 and regulates the other underframe 10 side engaging claw 35 fitted in the fitting object part 23 so as not to engage with the engaging hole 26 of the fitting object part 23 when two respective underframes 10 are vertically stacked by its connecting parts 20, is integrally formed. |
