PURPOSE: A wiper blade assembly having a single elastic support member is provided to reduce frictional resistance, and to improve endurance by covering a single rail spring with double rubber structure. CONSTITUTION: Blade rubber(100) is composed of first rubber(110) having high stiffness, and second soft rubber(120). A single elastic member is formed in a wiper blade assembly with assembling the blade rubber with curved rods of the wiper. A single rail spring(50) is placed in the first rubber, and a first base part(112) is formed. The first base part has a space(113) to cover a second base part(124) of the second rubber. The second rubber and the first rubber are manufactured individually, and the second rubber is covered with the first rubber by inserting a fixing sill(111) of the first rubber to a fixing groove(122) of the second rubber. The wiper blade is contacted to the windshield of the vehicle with arranging the rail spring in the blade rubber. Noise is reduced in operating the wiper, and endurance is improved with reducing frictional resistance.
