- the size of the insertion opening 214 specifically, the distance from the bridge portion 222 to the bottom surface 212 just below it, is slightly narrower than the thickness of the radar main body 122 so that the radar main body 122 can be gripped between them.
- a projection 226 that fits into the radar main body 122 that has been inserted is provided on the bottom surface 212 side of the bridge portion 222.
- Two slopes 216 and 218 are provided on the bottom surface 212. These slopes 216, 218 are for guiding the radar main body 122 to the back of the insertion port 214, and the slope 216 is provided at the inlet side end of the bottom surface 212, and the slope 218 is below the bridge portion 222.
- the bottom surface 212 is provided at a location where the height is raised.
- the bottom surface 212 comes into contact with the back surface 131 that is the back side of the transmission / reception surface 130 of the radar main body portion 122, and the back surface 131 slides on the bottom surface 212.
- the radar main body 122 rides on a slope 218 provided near the lower portion of the bridge portion 222, and assumes an oblique posture so as to avoid the protruding portion 226.
- a slope 216 is provided at the end of the bottom surface 212 on the entrance side so that the oblique posture can be suitably taken so as not to interfere with the inclined radar main body 122. In this manner, in the case 202, the slopes 216 and 218 are provided, so that the radar main body 122 can be smoothly inserted and held by the bridge portion 222 and the bottom surface 212.
- the radar installation part 204 is provided in the vicinity of the fixed part 150 of the fascia retainer 120 so that the radar main body 122 can stably exhibit its radar performance.
- the fixing part 150 is a part that is fixed to the side panel 126 (FIG. 2B) using bolts, clips, or the like.
- the vicinity of the fixed portion 150 is a portion that is not particularly easily affected by the vibration of the bumper fascia 108 in the fascia retainer 120 during traveling of the vehicle. Therefore, by providing the radar installation part 128 in the vicinity, the influence on the radar main body 122 due to vibration can be suppressed.
- the present invention can be used for an on-vehicle radar installation structure in which a radar main body is installed near a bumper of a vehicle, and a fascia retainer that attaches a bumper fascia that is an exterior part of the bumper to the vehicle main body.

Abstract
Description
図6は、図3に例示した車載用レーダ102の変形例を例示した図である。図6(a)は、図3(b)に対応して、変形例である車載用レーダ200を例示した図である。図6(a)に例示する車載用レーダ200は、レーダ本体122を収容するケース202を備え、このケース202を介してレーダ本体122をレーダ設置部204に組み付けている点において、図3(a)の車載用レーダ102と構成が異なっている。なお、以下では、図1~5を参照して既に説明した構成要素は、同じ符号を付することによってその説明を省略する。
