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.

Abstract: An electric air pump is provided that includes (i) a motor that includes a rotary shaft provided with a worm, (ii) a crank that includes a worm wheel which engages with the worm and a rod with one end rotatably coupled to the worm wheel, and (iii) a piston that is housed in a cylinder extending along an axial direction of the motor, that is coupled to another end of the rod and moves back and forth along an extension direction of the cylinder due to actuation of the crank, and that ejects air inside the cylinder from a valve provided at one end of the cylinder due to being moved toward the one end side of the cylinder.
