<P>PROBLEM TO BE SOLVED: To provide a washer nozzle with a check valve which secures the sealing performance of a nozzle body and enables maintenance and repair inside the nozzle body. <P>SOLUTION: In the washer nozzle 10 with the check valve, the fixing portion 62 of an O-ring valve 60 is clamped and fixed between the bottom surface of a joint portion 34 and the bottom surface of a clamp hole 20 by the attachment of a lower body 14 and an upper body 32 through the attachment of the joint portion 34 to a joint hole 18 and the engagement of engagement protrusions 36 with engagement holes 30, and an attached region between the joint hole 18 and the joint portion 34 is sealed. Accordingly, the sealing performance of the nozzle body 12 is secured even when the lower body 14 is not fixed to the upper body 32. The lower body 14 and the upper body 32 are disassembled, even after the lower body 14 is attached to the upper body 32, by separating the engagement protrusions 36 from the engagement holes 30 and by separating the joint portion 34 from the joint hole 18, thereby the maintenance and the repair inside the nozzle body 12 are enabled. <P>COPYRIGHT: (C)2003,JPO |
