A disclosed sound absorber for a tire comprises: a plurality of first bodies which are separated from an inner liner and are placed at a regular interval along a rotational direction of the tire; a plurality of second bodies which are placed on one side of the first body and are engaged with the inner liner; a plurality of first connection units which couple the first bodies and the second bodies for the first bodies and the second bodies to rotate relatively; a plurality of third bodies which are placed on the other side of the first body and are engaged with the inner liner; and a plurality of second connection units which couple the first bodies and the third bodies for the first bodies and the third bodies to rotate relatively. The sound absorber reduces an area attached on the inner liner inside the tire and at the same time, reduces noise while not being damaged on an uneven road surface.

    개시되는 타이어용 흡음재는 이너라이너에서 이격되고 타이어의 회전방향을 따라 동일한 간격으로 배치되는 복수의 제1몸체; 제1몸체의 일측에 배치되고 이너라이너에 결합되는 복수의 제2몸체; 제1몸체와 제2몸체가 상대적으로 회전할 수 있도록 제1몸체와 제2몸체를 결합하는 복수의 제1연결부; 제1몸체의 타측에 배치되고 이너라이너에 결합되는 복수의 제3몸체; 및 제1몸체와 제3몸체가 상대적으로 회전할 수 있도록 제1몸체와 제3몸체를 결합하는 복수의 제2연결부를 포함할 수 있으므로, 타이어 내부의 이너라이너에 부착되는 면적을 줄일 수 있는 동시에 고르지 못한 노면에서도 파손되지 않고 소음을 감소시킬 수 있다.
