PURPOSE: A corrosion preventing device for a joint unit of a post of a power-transmission, transformation, and distribution steel tower is provided to prevent water penetration by the installation of a rubber gasket between a second cylindrical part and a steel tower post. CONSTITUTION: A corrosion preventing device for a joint unit of a post of a power-transmission, transformation, and distribution steel tower comprises a main body(100) and a fitting cover(200). The main body comprises first and second cylindrical parts(110,130), an inclined part(120), and a pair of fastening ribs(140). The inclined part is extended at an incline from the top end of the first cylindrical part. The second cylindrical part is vertically and upward extended from the inclined part to cover a steel tower post(10). Fastening bolts(141) and nuts(142) are installed in multiple fastening holes of the fastening ribs. The fastening ribs are inserted into fitting grooves(201) of the fitting cover.
