ABSTRACT:
A warpage correcting construction for an electrical connection box including upper and lower casings molded by synthetic resin, comprising: a first locking claw projecting outwardly from an outer peripheral wall of the upper casing and including an upper end engagement face, a depression face and an oblique face; and a second locking claw projecting inwardly from an outer peripheral wall of the lower casing and including a lower end engagement face, a distal end face and an oblique face; the upper end engagement face of the first locking claw having a projecting distance larger than that of the lower end engagement face of the second locking claw so as to cause the depression face of the first locking claw to outwardly depress the outer peripheral wall of the lower casing at the time of engagement between the upper end engagement face of the first locking claw and the lower end engagement face of the second locking claw such that inward warpage of the outer peripheral wall of the lower casing is corrected.
