Patent abstract

A liquid level detecting apparatus has an ultrasonic sensor, a reflector, a first pipe and a second pipe. The reflector reflects an ultrasonic wave from the ultrasonic sensor to a liquid level, and the ultrasonic sensor detects a reflection wave reflected on the liquid level to detect a liquid level position. The first and second pipe surrounds the ultrasonic wave transmission path from the ultrasonic sensor via the reflector to the liquid level. The first pipe and the second pipe are integrally configured and supported on a bottom of a tank to be rotatable about the first pipe.
