合部が受けなくて済む。Therefore, like the conventional electric junction box 50,
There is no need to form many types of bases according to the harness to be connected. Therefore, the manufacturing cost of the electric junction box can be reduced. Further, even if the base 11 is not formed to the prescribed size as in the conventional case, the harness covers 25, 2 can be formed.
When assembling the lower case 12 to the lower case 12, such a dimensional error does not adversely affect the assembling.
However, if the harness covers 25 and 26 are assembled to the lower case 12 without being affected by the dimensional change of the base 11, even if the harness covers 25 and 26 are assembled to the lower case 12, it is possible to use the material. Furthermore, when the base 11 is deformed after assembling the electric junction box, the effect of the deformation does not need to be exerted on the engaging portions between the harness covers 25 and 26 and the lower case 12.
