To provide a wiper blade rubber that prevents the occurrence of squeal noise, has excellent loss coefficients (tanδ) in a wide temperature range, and has small tensile permanent elongation.SOLUTION: A wiper blade rubber contains at least one thermosetting rubber selected from the group consisting of isoprene rubber and chloroprene rubber. When the at least one thermosetting rubber is 100 pts.mass, the wiper blade rubber contains a liquid polyolefin having no unsaturated bond in the molecule of 5 pts.mass or more and 15 pts.mass or less and carbon black.SELECTED DRAWING: None

    【課題】スキールノイズの発生がなく、広い温度範囲で損失係数(tanδ)に優れ、引張永久伸びの小さいワイパーブレードゴムを提供する。【解決手段】イソプレンゴムおよびクロロプレンゴムからなる群より選択される少なくとも一種の熱硬化性ゴム100質量部に対し、分子中に不飽和結合を含まない液状ポリオレフィンを5質量部以上15質量部以下とカーボンブラックとを配合したワイパーブレードゴム。【選択図】なし
