PROBLEM TO BE SOLVED: To provide a resonator that enables suppression of a mounting area and that can easily secure the capacity of an auxiliary air chamber.SOLUTION: The resonator includes a resonator body 36 having a longitudinal direction in the circumferential direction of a wheel and an auxiliary air chamber 46 formed therein. The resonator body 36 includes: a bottom plate portion 41 opposing to a rim surface of the wheel; an upper plate portion 42 located on the side opposite to the rim surface relative to the bottom plate portion 41 and connected to the bottom plate portion 41 on both sides to partition the auxiliary air chamber 46; and lock portions 44 extending from both sides of the upper plate portion 42 to the side opposite to the rim surface. The lock portions 44 are locked on holding portions opposing to the rim surface. This structure can suppress a mounting area in both side directions compared to the case where the lock portions are extended laterally. Since width of the resonator body 36 per the mounting area can be increased, an increase in the capacity of the auxiliary air chamber 46 within the resonator body 36 can be easily secured.

    【課題】取り付け面積を抑制し、副気室の容量を容易に確保できるレゾネータを提供する。【解決手段】ホイールの周方向に沿って長手方向を有し、内部に副気室46を設けたレゾネータ本体36を備える。レゾネータ本体36は、ホイールのリム面に対向する底板部41と、底板部41に対してリム面と反対側に位置し、底板部41と両側部で連結して副気室46を区画する上板部42と、上板部42の両側部からリム面と反対側に延出する係止部44とを有する。係止部44を、リム面に対向する保持部に係止する。係止部を側方へと延出する場合よりも両側方向の取り付け面積を抑制できる。取り付け面積当たりのレゾネータ本体36の幅を大きくできるので、レゾネータ本体36の内部の副気室46の容量を容易に大きく確保することが可能となる。【選択図】図1
