ABSTRACT:
An obstacle detection device has an ultrasonic sensor fixed to a first side of a mount member. The ultrasonic sensor sends/receives ultrasonic wave toward/from a second side of the mount member, which is opposite to the first side thereof. At least one of a mounting surface of the ultrasonic sensor and a mounting surface of the mount member has a protrusion, which protrudes therefrom so that an end surface of the protrusion contacts the other of the mounting surfaces. The mounting surfaces of the mount member and the ultrasonic sensor face each other. The end surface of the protrusion and the mounting surface of the ultrasonic sensor are different from each other in at least one of shape and area thereof.
