Disclosed is a sound absorber for a tire, which comprises: a plurality of bodies arranged at a constant interval in a rotary direction of a tire and having a cross-section with an arch shape; and a plurality of protrusions formed to be sharp on a lower surface of the body for a noise. The protrusion comprises: a first surface of which a portion of a surface is formed to be concave or convex; a second surface of which a portion of a surface positioned on one side of the first surface is formed to be concave or convex; and a third surface of which a surface positioned between the first surface and the second surface is formed to be concave or convex. The body can reduce an area attached to an inner liner inside the tire, and at the same time, the protrusion can reduce the noise.

    개시되는 타이어용 흡음재는 타이어의 회전방향을 따라 동일한 간격으로 배치되고 단면이 아치형인 복수의 몸체; 및 소음을 위해 몸체의 하면에 뾰족하게 형성되는 복수의 돌기를 포함하고, 돌기는, 표면의 일부가 오목하거나 볼록하게 형성되는 제1면; 제1면의 일측에 위치하는 표면의 일부가 오목하거나 볼록하게 형성되는 제2면; 및 제1면과 제2면 사이에 위치하는 표면이 오목하거나 볼록하게 형성되는 제3면을 포함할 수 있으므로, 몸체가 타이어 내부의 이너라이너에 부착되는 면적을 줄일 수 있는 동시에 돌기가 소음을 감소시킬 수 있다.
