Abstract

PURPOSE: To prevent the insulation failure of electric parts by providing a shielding means inside a lower pole to prevent the water infiltrating from a joint between a lower pole and an upper pole from flowing into a core pole in an illumination pole device. CONSTITUTION: In an illumination pole device, a lid 7 to which a submergence preventing plate 8a adopted as a shielding means 8 is fixed is installed in the opening 2a of a lower pole 2 containing a core pole 1. The water which infiltrates into the inner part of the lower pole 2 from a joint 3a between the lower pole 2 and an upper pole 3 and is dripped inside the core pole 1 from an operating window 1e through the outer surface of the flat part 1f of the core pole 1 and the outer wall of the core pole 1 is dripped in the submergence preventing plate 8a adopted as the shielding means 8. It is prevented that water flows on the submergence preventing plate 8a in the direction of the lid 7 which is the outside of the core pole 1 and is applied to a switch 6 which is an electric part, thereby preventing the lowering of the insulation of the electric part. As a result, the coating of the joint 3a between the lower pole 2 and the upper pole 3 becomes unnecessary at the time of the construction.
