Title: ULTRASONIC SENSOR
Abstract:
A vibration suppressing member (6) is disposed on a rear surface (4d) of a flange (4a) of a bezel (4). Adopting such a configuration makes it possible to suppress the transmission of vibrations from an ultrasonic transducer (10) to a position in which an ultrasonic sensor (1) is attached. Reverberation after an ultrasonic wave has been output from the ultrasonic transducer (10) can therefore be attenuated in a short time, making it possible to prevent erroneous detection that a reflected wave has been received, caused by the existence of reverberation.
