PROBLEM TO BE SOLVED: To automatize the molding and assembling of parts using an injection molding die, in a washer liquid jetting nozzle. SOLUTION: A seal valve part 43 coming into close contact with a valve seat part 21 formed in a nozzle body member 20 from the downstream side is formed. When a washer liquid reaches the valve seat part 21 by driving a washer pump, the seal valve part 43 is displaced to the downstream side by the water pressure to open the valve seat part 21. When the operation of the washer pump is stopped and the water pressure of the washer liquid is not applied, the seal valve part 43 is displaced to the valve seat 21 side by the elasticity given by a supporting film 42 to seal the valve seat part 21 again. As a result, the washer liquid is sealed between the discharge port of the washer pump and the valve seat part 21 including a tube and is sprayed with switching-on without the loss of time. All parts are molded with the injection molding die and automatically assembled in the die. COPYRIGHT: (C)2004,JPO
