ウォッシャノズル１５０が提案されている。To solve this problem, a washer nozzle with a check mechanism has been devised. For example, FIG.
As shown in the figure, the nozzle body is made of two parts, an upper and lower resin upper body 112 and a lower resin body 114, and a spring 118 and a spring 1 are provided in a cleaning liquid supply passage 112c on a supply port 112a side formed in the upper body 112.
A plate 120 receiving the urging force of 18 and a valve 116 made of an elastic material are arranged, and then a lower body 114 having a cleaning liquid supply path 114a and a contact surface with the valve 116 at the center is ultrasonically welded to the upper body 112. In a normal state in which an electric pump (not shown) does not operate, the energized valve 116 closes the cleaning liquid supply passage 114a and reverses the outflow of the cleaning liquid.
Has been proposed. Further, as shown in FIG. 4, a spring 158 and a metal valve 156 are disposed in a cleaning liquid supply passage 152c on the supply port 152a side formed in the upper body 152, and thereafter, the cleaning liquid supply passage 154a and The lower body 154 having an abutting surface with the valve 156 is ultrasonically welded to the upper body 152. In a normal state where the electric pump does not operate, the energized valve 156 closes the cleaning liquid supply path 154a to prevent the cleaning liquid from flowing out. A non-returning washer nozzle 150 has been proposed.

Since the latter washer nozzle 150 uses the metal valve 156, the checker function is poor. further,
In both cases, the upper and lower upper bodies 112 and 152 and the lower bodies 114 and 154 need to be joined by ultrasonic welding, which has been a factor of increasing the cost of the washer nozzle.
