Abstract
An onboard optical sensor cleaning device ejects fluid against a sensing surface of an onboard optical sensor installed in a vehicle and removes foreign matter from the sensing surface. The onboard optical sensor cleaning device includes a cleaning liquid ejection port that ejects supplied cleaning liquid and an air ejection port that ejects supplied air. The cleaning liquid ejection port and the air ejection port are independent from each other, an air ejection axis of the air ejection port is set so that the ejected air mixes with the cleaning liquid ejected from the cleaning liquid ejection port and to be directed toward the sensing surface.
