To provide a fender insulator capable of efficiently reducing not only high-frequency noise but also cavernous resonance of a tire with tire deformation in irregular travel, and low-frequency noise caused by a tire house during vehicle travel.SOLUTION: A vertically long fender insulator FS arranged in the vertical direction between a pillar 71 and a fender 72 of a vehicle includes: an insulator body 1 comprising a soft polyurethane foam forming the outer shape of the fender insulator FS; a box-shaped resonator volume part 3 integrally embedded in the insulator body 1; and a communication pipe 4 whose base end 41 is connected to the resonator volume part 3, which exposes a pipe opening 420 of a tip end 42 from the insulator body 1, and in which the pipe opening 420 directs a vehicle front side by mounting on the vehicle.SELECTED DRAWING: Figure 4

    【課題】高周波騒音のみならず、凹凸走行のタイヤ変形に伴うタイヤの空洞共鳴音や、車両走行中のタイヤハウスに起因する低周波域の騒音も効率良く低減することができるフェンダーインシュレータを提供する。【解決手段】車両のピラー71とフェンダー72との間で、上下方向に配設される縦長のフェンダーインシュレータFSにおいて、フェンダーインシュレータFSの外形を形成する軟質ポリウレタン発泡体からなるインシュレータ本体1と、インシュレータ本体1に埋設一体化されたボックス状のレゾネータ容積部3と、レゾネータ容積部3に基端41がつながり、先端42の管口420をインシュレータ本体1から露出させ、且つ車両への取付けで、管口420が車両前方側に向く連通管4と、を具備する。【選択図】図4
