Abstract
A noise reduction device (10) according to the present technology includes a band member (11) made of a thermoplastic resin formed into a ring shape along a tire inner surface, and a sound absorbing member (12) made of a porous material bonded to the band member (11). The sound absorbing member (12) is arranged to be fitted onto the tire inner surface with the help of an elastic restoring force of the band member (11), the band member (11) includes at least one raised portion (14) provided on an outer circumferential surface thereof, and the outer circumferential surface of the band member (11) has a contact area when in contact with a smooth surface in a range of from 10% to 80% of the projected area of the band member (11).
