To provide a seat rubber with a novel structure capable of more highly suppressing generation of noise without impairing a supporting function of a coil spring.SOLUTION: In a seat rubber 10, a central projection 24 projecting toward inside a coil spring 12 is disposed at a central portion; a seat receiving part 26, which expands on an outer peripheral side of a base end side of the central projection 24 and on which a lower end 14 of the coil spring 12 is stacked, and which is disposed continuously extending in a peripheral direction; on an upper surface 36 of the seat receiving part 26, a step-shaped part 34 is disposed at a peripheral position corresponding to a winding end 32 of the coil spring 12; the upper surface 36 of the seat receiving part 26 is an inclination surface gradually inclining downward toward a lower side of the step-shaped part 34 in the peripheral direction opposite to the step-shaped part 34 from an upper side of the step-shaped part 34; and a radial groove 54 which extends in the radial direction of the seat receiving part 26 on the lower side of the step-shaped part 34 and is open at an outer peripheral end, is formed in the upper surface 36 of the seat receiving part 26.SELECTED DRAWING: Figure 1

    【課題】コイルスプリングの支持機能を損なうことなく、異音発生をより高度に抑えることのできる、新規な構造のシートラバーを提供する。【解決手段】シートラバー10において、中央部分にはコイルスプリング12の内側に向けて突出する中央突部24が設けられており、中央突部24の基端側の外周側に広がってコイルスプリング12の下端14が重ね合わされる受座部26が周方向へ連続的に延びて設けられており、受座部26の上面36には、コイルスプリング12の巻線端32に対応する周方向位置に段差状部34が設けられており、受座部26の上面36は、段差状部34の上側から段差状部34と反対の周方向で段差状部34の下側に向かって次第に下方へ傾斜する傾斜面とされており、受座部26の上面36には、段差状部34の下側において受座部26の径方向に延びて外周端に開放された径方向溝54が形成されている。【選択図】図1
