Such an ultrasonic sensor radiates (transmits) an ultrasonic pulse into the air and receives a reflected wave generated by the transmitted ultrasonic wave being reflected by an obstacle (such as a detection target). Then, after the ultrasonic wave received by the ultrasonic sensor is processed as a reception signal, an alarm or the like is issued based on the reception signal, so that the driver can recognize the existence of the obstacle.

すると、上記の問題は解消しないものであった。However, in the mounting structure of the ultrasonic sensor A as described above, the ultrasonic vibrator 11
There is an opening 15 of the horn portion 16 on the front side (front side) of the horn, so that rainwater or snow and dust easily accumulate in the dent of the opening 15 during traveling or the like. ) Changes, the detection characteristics change, and there is a problem in that the detection area of the ultrasonic sensor A changes and there is a false alarm as if there is an obstacle even though there is no obstacle in the detection area. Further, the horn portion 16 and the projecting piece 17 project from the surface of the bumper 51 and the horn portion 16
As a result, the surface of the bumper 51 has concavities and convexities, which causes a problem that the appearance is deteriorated. Therefore, without using the horn to control the ultrasonic beam, we use an ultrasonic transducer that can control the thickness of the beam in the horizontal and vertical directions, and use the ultrasonic transducer alone to achieve the above directional characteristics. Although an ultrasonic sensor having such an ultrasonic transducer has been formed, the above problem has not been solved even if such an ultrasonic transducer is used and the housing 6 shown in FIG. 10 is employed.
