PROBLEM TO BE SOLVED: To provide a mounting structure for an ultrasonic transducer detecting an existence of a close-range obstacle with immediately converging reverberation vibration propagating from a bumper to a vibrator after ultrasonic transmission. SOLUTION: The ultrasonic transducer detects an existence of an obstacle by receiving a reflected wave of ultrasonic wave emitted from a vibrator 2. The vibrator 2 is attached to a vibrator attachment portion 12, provided at a rear surface 11a of a bumper 11, through an elastic member 14. COPYRIGHT: (C)2011,JPO&INPIT |
