Abstract

In an ultrasonic wave utilizing device having a cylindrical elastic holder 2 into which an ultrasonic sensor 3 is pressed and a cylindrical part 23 that is closed at one end and is formed in a case 1 in such a way as to have this elastic holder 2 assembled therein, the elastic holder 2 has an elastic end wall 33 formed at an end of pressing side, a first elastic retaining part 35 for retaining the outside end edge of the cylinder part of the pressed-into ultrasonic sensor 3, and a second elastic retaining part 36, 37.

Claims

1. An ultrasonic wave utilizing device comprising:

a cylindrical elastic holder into which an ultrasonic sensor is pressed; and

a cylindrical part that is closed at one end and is formed in a case in such a way as to have the elastic holder assembled therein, characterized in that

the elastic holder has an elastic end wall formed at an end of pressing side and a first elastic retaining part for retaining an outside end edge of the ultrasonic sensor which is pressed into the elastic holder.

2. The ultrasonic wave utilizing device as claimed in claim 1, wherein the elastic holder has a second elastic retaining part retained by the case on the elastic end wall.

3. The ultrasonic wave utilizing device as claimed in claim 2, wherein the second elastic retaining part has an elastic pillar-shaped part that is passed through a hole formed in a bottom of the cylindrical part and an elastic bulging part that is formed on the elastic pillar-shaped part in a manner bulging in a radial direction such that it is passed through the hole and then retained by an edge of the hole.
