Abstract: An air conditioner has: an air-conditioning case including an air passage; a plate-shaped door body that rotates about a rotation shaft; and an opposing wall provided in the air passage to define a gap between a tip portion of the door body and the opposing wall. A length of the opposing wall in a circumferential direction of the rotation shaft is larger than a thickness dimension of the tip portion of the door body. The opposing wall includes a first door facing surface and a second door facing surface. The air-conditioning case has a connecting surface connecting the first door facing surface and the second door facing surface. The second door facing surface is located outward with respect to the rotation shaft in a radial direction than the first door facing surface is.

Abstract: An ultrasonic sensor is provided with an ultrasonic element that converts between an electrical signal and an ultrasonic vibration and an element accommodating case having a bottomed cylindrical shape and accommodating the ultrasonic element inside thereof. The element accommodating case includes a side plate portion formed in a cylindrical shape that surrounds a directional center axis, and a bottom plate portion that closes one end side of the side plate portion in an axial direction which is parallel to the directional center axis. The ultrasonic element is attached to the bottom plate portion. The bottom plate portion includes at least one protrusion. The protrusions vibrate together with the bottom plate portion when the bottom plate portion vibrates as an ultrasonic vibration.
