Abstract: A box (4) has, on a rear wall surface (4b) facing a plane where an opening (4a) is formed, a first protrusion (4g) which is fitted to a first notch (3a) of a substrate (3) and first ribs (4h) which support a first end of the substrate (3) by sandwiching the first end, and has, on two surfaces facing respective substrate surfaces of the substrate (3), a hole (4n) for each of the two surfaces. A lid (5) has, on a lid surface (5a) facing the opening (4a), a second protrusion (5b) fitted to a second notch (3b) of the substrate (3), a second rib (5c), and a third rib (5d), the second and third ribs supporting a second end of the substrate (3) by sandwiching the second end, and has, at an outer periphery, hooks (5g) for fixing the lid (5) to the box (4) by being fitted to the holes (4n) of the box (4). The hooks (5g) each have an inclined surface (5j) that allows the lid (5) to move by a specified amount in a direction in which the lid (5) comes off from the box (4).

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.

Abstract: A case of tilt angle measuring apparatus is composed of a case body for housing ultrasonic sensors and a cover for covering a top of the case body, and the case body includes a bottom plate having windows for exposing the ultrasonic wave transmitting/receiving faces of the ultrasonic sensors, a side plate extending upward from the peripheral edge of the bottom plate and abutting against the bottom surface of the cover, and horn parts extending downward from the bottom plate so as to surrounding the windows.

Abstract: A cap is fit to a sensor case having a sensor-mounting hollow portion integrally formed therewith into which an ultrasonic sensor is fit. A plate spring is fit onto an outside of the sensor case to engage the plate spring with the cap. This plate spring integrally holds together both the sensor case and the cap. Having been constructed as above, the invention provides an easy integral assembly of a sensor case and a cap by means of a single plate spring and exhibits the ability for mounting and fixing the detector to a bumper or the like of a vehicle.

Abstract: A ultrasonic transceiver includes a case for housing a ultrasonic sensor having a transducer provided therein, and a resilient member to be interposed between the case and an ultrasonic sensor. The surface of the case opposing the side surface of the ultrasonic sensor is tapered with respect to the surface of the ultrasonic sensor without involvement of the resilient member.
