PROBLEM TO BE SOLVED: To provide an ultrasound sensor that can reduce its height projecting to the outside of a bumper and can be easily positioned with respect to the bumper.SOLUTION: An ultrasound sensor includes: a mount 2 to be fixed to an inner surface of a bumper 1; and a sensor body 3 that is to be inserted to an exposure hole 11 provided in the bumper 1, and that is to be joined to the mount 2 by engagement of a projection and a recess. The sensor body 3 can be moved parallel to the mount 2 so that its projecting height to the outside of the bumper 1 becomes large than that at a position where it is joined by the engagement of the projection and the recess. Compared with a case where the sensor body is fixed to the bumper 1 by pinching the bumper 1 from the outside and inside, its projecting height to the outside of the bumper 1 can be reduced as shown in Fig. 1(b). Inserting the sensor body 3 to the exposure hole 11 in a state where its projecting height from the mount 2 is set large as shown in Fig. 1(a) allows the mount 2 to be relatively easily positioned with respect to the bumper 1. |
