A resonator (30) engages with the outer circumferential surface of a rim (21) of a wheel (20), and is thus affixed to said outer circumferential surface. The resonator (30) has a main body portion (31) in which a long resonance space (S) that extends along the outer circumferential surface of the rim (21) is incorporated, and an opening portion (34), formed in the main body portion (31), that connects at least one among both ends of the resonance space (S) in the extension direction to outside of said resonance space (S). The resonance space (S) and the opening portion (34) constitute a resonance tube.
谐振器(30)通过与车轮(20)的轮辋(21)的外周面卡合而固定于该外周面。谐振器(30)具有:主体部(31),内置沿着轮辋(21)的外周面延伸的长条状的共鸣空间(S);和开口部(34),形成于主体部(31),使共鸣空间(S)的延设方向的两端的至少一方与该共鸣空间(S)的外部连通。共鸣空间(S)和开口部(34)构成共鸣管。
