PROBLEM TO BE SOLVED: To improve weather resistance by preventing corrosion of a case attaching portion due to sunshine or rainfall in an outdoor case of electronic equipment. SOLUTION: A rib 7 surrounding a case attaching portion 5 is provided in the bottom portion of an outdoor case 1, which is placed along a bracket 14. An external screw member 21 is threadedly engaged to an internal screw 11 of the case attaching portion 5 to attach the outdoor case 1 to the bracket 14. At this time, the rib 7 is disposed in the vicinity of the attached surface 19 of the bracket 14, so as to be a protective wall portion for preventing rainwater from entering the hub 6 side or sunlight from irradiating the hub 6. Consequently, stress corrosion of the hub 6, the internal screw member 11 and the external screw 21 is prevented and thereby weather resistance is improved.
