PROBLEM TO BE SOLVED: To provide a noise reduction device for a tire that, even in high speed travelling such as 300 km per hour or more of a vehicle equipped with tires for high-speed travelling, can suppress a band member from being plastically deformed due to heat of the tires and exhibit sufficiently a noise reduction function even during the high speed travelling, and a pneumatic tire comprising the noise reduction device.SOLUTION: A noise reduction device for a tire comprises a sound absorption material formed of a porous material and a band member for attaching the sound absorption material to the inner surface of the tire, where the band member is constituted of thermoplastic resin and a heat-proof reinforcement layer is provided on at least one part in a tire circumferential direction of the band member.

    【課題】高速走行用タイヤで、時速300km以上などの高速走行をしたときであっても、タイヤの熱によるバンド部材の塑性変形を抑止することができ、そうした高速走行のもとでも騒音低減機能を十分に発揮することができるタイヤ用騒音低減装置と、該騒音低減装置を備えた空気入りタイヤを提供する。【解決手段】多孔質材料からなる吸音材と、該吸音材をタイヤ内面に装着するためのバンド部材を備えたタイヤ用騒音低減装置において、前記バンド部材を熱可塑性樹脂で構成するとともに、該バンド部材に対して、耐熱性補強層をタイヤ周方向上で少なくとも一部に設けたタイヤ用騒音低減装置。【選択図】図1
