CONSTITUTION: A windshield cleaning apparatus is built in a seal member 7 for the windshield 8. Nozzles 9 are disposed on four sides of the seal member 7 of the windshield 8 in such a way that the nozzles 9 are reliably fixed to their position and change in setting state on the windshield 8 is prevented. A supplier for supplying nozzles 9 with washing liquid is incorporated in the seal member 7. A cleaning apparatus is mounted by connecting the seal member 7 in a liquid path which is provided with a reservoir and a pump and through which washing liquid is supplied through a quick connector. The liquid path part in the seal member 7 is provided with a groove 12 in which a pipeline 13 is inserted and a channel 14 is formed in the direction of thickness of the seal member 7 to enable the pipeline 13 to the nozzles 9.
