Patent ID: 7591182

Claim:
An ultrasonic sensor mounting structure, comprising: an ultrasonic sensor that includes an ultrasonic transducer for generating a vibration and a vibrating surface for emitting the vibration; and a wall member having an inner surface and an outer surface opposite to the inner surface, the inner surface having a fixation portion where the ultrasonic sensor is fixed so that the ultrasonic sensor is not visible from the outer surface of the wall member, a touch portion where the ultrasonic transducer directly or indirectly touches so that the vibration generated by the ultrasonic transducer is transmitted to the touch portion, and a location mark portion that defines the fixation portion, the outer surface having a vibration portion positioned corresponding to the touch portion so that the vibration propagates from the touch portion to the vibration portion through the wall member, wherein the location mark portion is located outside the touch portion.
