PURPOSE:To easily recognize the wear of rubber by forming the surface of a section, adjacent to the glass surface, of a wiper blade, using a color of a different system from the color of the blade rubber main body. CONSTITUTION:The rubber main body section 23 of wiper blade rubber 2 and its lip section side 21 are molded by being color-separated in quite different colors by way of two-layered molding. If a lip edge section 22 that is adjacent to the glass surface is abraded and the wiping performance of the wiper blade is deteriorated, the wear amount of the lip can easily be recognized since the color of the rubber main body 23 that is quite different from the color of the lip section side 22 is displayed on the surface. |
