To suppress vibration transmission as much as possible between an ultrasonic sensor and a vehicle body component to which the ultrasonic sensor is attached.SOLUTION: A sensor fixture (7) is used to attach an ultrasonic sensor including a columnar ultrasonic microphone (5) extending along an axial direction parallel to a central axis (CL) to a plate-like vehicle body component (V3). The sensor fixture includes a cylindrical part (72). The cylindrical part is provided so as to surround the ultrasonic microphone and be housed in a through hole (V5) formed in the vehicle body component in an in-vehicle state in which the ultrasonic sensor is attached to the vehicle body component. A through hole facing part (78), which adjacently faces, in a radial direction radially extending from the central axis, an inner edge (V51) of the through hole so as to be capable of coming into contact with each other in the in-vehicle state in the cylindrical part, includes an area reduction structure which can reduce a contact area with the inner edge.SELECTED DRAWING: Figure 7

    【課題】超音波センサとその取付対象である車体部品との間の振動伝達を可及的に抑制すること。【解決手段】センサ取付具(7)は、中心軸線(CL)と平行な軸方向に沿って延設された柱状の超音波マイクロフォン(5)を有する超音波センサを板状の車体部品(V3)に取り付けるために用いられる。このセンサ取付具は、筒状部(72)を備えている。筒状部は、超音波マイクロフォンを囲みつつ、超音波センサを車体部品に取り付けた車載状態にて車体部品に形成された貫通孔(V5)に収容されるように設けられている。筒状部における、車載状態にて貫通孔の内縁(V51)と接触可能に、中心軸線から放射状に延びる径方向に近接対向する貫通孔対向部(78)は、内縁との接触面積を低減する面積低減構造を有する。【選択図】図7
