PROBLEM TO BE SOLVED: To provide an on-vehicle optical sensor cleaning device which efficiently attains high cleaning performance.SOLUTION: An on-vehicle optical sensor cleaning device jets air from an air jetting port 7 of a second nozzle unit 8 to a lens surface of an on-vehicle camera mounted on a vehicle to remove foreign objects adhering to the lens surface. The second lens unit 8 includes: a movable nozzle member 10 having the air jetting port 7; and a housing member (a case 9 and a base end closing member 11) which supports the movable nozzle member 10 so that the movable mozzle member 10 can move forward and rearward. The housing member includes: a jetting air introduction port 12a communicating with the air jetting port 7 of the movable nozzle member 10 in at least a state where the movable nozzle member 10 moves forward; and a forward movement air introduction port 17a which communicates with a sealing part 16 defined by a base end part of the movable nozzle member 10.SELECTED DRAWING: Figure 5
【課題】効率良く高い洗浄性能を得ることができる車載光学センサ洗浄装置を提供すること。【解決手段】車載光学センサ洗浄装置は、車両に搭載される車載カメラのレンズ面に第二のノズルユニット8の空気噴射口7から空気を噴射して、該レンズ面に付着した異物を除去する。第二のノズルユニット8は、空気噴射口7を有する可動ノズル部材10と、可動ノズル部材10を前後進可能に支持するハウジング部材(ケース9及び基端閉塞部材11)とを備える。ハウジング部材は、少なくとも可動ノズル部材10が前進した状態で可動ノズル部材10の空気噴射口7と連通する噴射空気導入口12aと、可動ノズル部材10の基端部にて区画された密閉室16と連通する前進用空気導入口17aとを有する。【選択図】図5
