During the winter season, while conducting tests and investigations on problems such as the inability to properly spray the cleaning liquid onto the glass, many of the causes of nozzle failures during the winter were piled up so as to cover the nozzle body from the outside This is because the injection holes are blocked by snow, ice, etc., and the freezing proceeds sequentially from the injection hole side opening outside the vehicle toward the upstream side of the passage. It was confirmed that the state of freezing of the cleaning liquid in the located passage was rare.

As a result, snow, ice, and the like covering the nozzle body on the injection hole side cannot be efficiently melted. For this reason, there arises a problem that the heating element and a battery for supplying power to the heating element are increased in size.
