PROBLEM TO BE SOLVED: To provide a wiper blade rubber in which chatter and allophone do not generate over a long period of time, and favorable wiping performance can be maintained.SOLUTION: A wiper blade rubber 1 includes a thermosetting elastomer 2 and a spherical filler 3. An average particle diameter of the spherical filler 3 is at least 0.1 μm and at most 32 μm, and a percentage content of the spherical filler 3 is at least 1.0 vol.% and at most 40.2 vol.%. By the wiper blade rubber 1, a low friction coefficient is realized, chatter and allophone do not generate over a long period of time, and favorable wiping performance can be maintained. |
