VEHICLE ULTRASONIC SENSOR APPARATUS, AND METHOD FOR ASSEMBLING VEHICLE ULTRASONIC SENSOR APPARATUS

摘要

A vehicle ultrasonic sensor apparatus is provided with an ultrasonic sensor including an ultrasonic vibrator, and a holder member for housing the ultrasonic sensor. The ultrasonic sensor is mounted at a predetermined location of a vehicle bumper having an outer surface exposed to the outside and an inner surface positioned on the opposite side to the outer surface. At the predetermined location of the bumper, a bumper hole is provided in a front end direction from the inner surface toward the outer surface. The holder member has a holder member hole in the front end direction. A first portion of the ultrasonic sensor is housed in the bumper hole, while a second portion is housed in the holder member hole. The inner surface of the bumper includes a contact surface in contact with the holder member. The holder member is made of an elastic material and is integrated with an antivibration member which covers at least a part of a side surface of the ultrasonic sensor, with the second portion of the ultrasonic sensor housed in the holder member hole. The antivibration member includes a protruding end portion protruding beyond the contact surface of the bumper in the front end direction in such a manner as to be fitted in the bumper hole.
