PURPOSE:To prevent a wind shield glass from being stained in a wind shield glass cleaning device equipped with a cleaning fluid pipe line and a fresh water pipe line by making the pipe line resistance of the cleaning fluid pipe line greater than that of the fresh water pipe line. CONSTITUTION:A cleaning fluid pipe line 26 is formed with a cleaning fluid tube 16 and connecting branch 25 of a connector 18, and a fresh water pipe line 27 is formed with a fresh water tube 17 and the connecting section 22 of the connector 18. And as a whole, the cleaning fluid pipe line 26 is made smaller in diameter and longer than the fresh water pipe line 27. Furthermore, the pipe line resistance of the cleaning fluid pipe line 26 is made greater than that of the fresh water pipe line 27 by forming a bend angle theta. This constitution makes the quantity of cleaning fluid injection less than that of fresh water thereby making cleaning fluid hardly disperse. As a result, cleaning fluid can be positively sprayed within the wiping area of a front wind shield glass so as to prevent the wind shield glass from being stained.
