A washer nozzle includes a spread jet opening for basically jetting washer fluid in a predetermined direction of a vehicle; and a jet opening for accessorily and intensively jetting part of the washer fluid as a directional jet flow which is different from the spread flow basically jetted from the spread jet opening. The washer fluid is jetted and sprayed over a large area in a fan-shaped spread flow from the spread jet opening. Further, the washer fluid is intensively sprayed as the directional jet flow from the jet opening. Thus, sweeping performance of the washer nozzle and a washer apparatus is improved such that the directional jet flow is not substantially affected by airflow during high-speed driving so that the washer fluid is effectively utilized so as to be sprayed and supplied to areas that are prone to be left unwashed.

What is claimed is: 1. A washer nozzle for supplying washer fluid to a windshield glass of a vehicle, the washer nozzle comprising: a nozzle body mounted on the vehicle, wherein the nozzle body has a feed passage for introducing the washer fluid; a spread jet opening for basically jetting the washer fluid as a spread flow that is spread in a predetermined direction of the vehicle, the washer fluid being introduced from the feed passage; and a branch channel for introducing part of the washer fluid; and a jet opening for supplementally and intensively jetting the washer fluid as a directional jet flow, which is different from the spread flow basically jetted from the spread jet opening, the washer fluid being introduced from the branch channel, wherein the spread flow and the directional jet flow are produced simultaneously. 2. A washer nozzle for supplying washer fluid to a windshield glass of a vehicle, the washer nozzle comprising: a nozzle body mounted on the vehicle and having a feed passage for introducing the washer fluid; a nozzle element integrally assembled in the nozzle body so as to connect to the feed passage, and having a spread jet opening for basically jetting the washer fluid as a spread flow, which spreads in a lateral direction of the vehicle, the washer fluid being introduced from the feed passage; a branch channel for introducing part of the washer fluid fed from the feed passage; and a jet opening connecting to the branch channel for supplementally and intensively jetting the washer fluid as a directional jet flow, which is different from the spread flow basically jetted from the spread jet opening, the washer fluid being introduced from the branch channel, wherein the spread flow and the directional jet flow are produced simultaneously. 3. The washer nozzle according to claim 2, wherein the nozzle element includes an oscillation chamber for self-oscillating a mainstream of the washer fluid introduced from the feed passage, and wherein the spread jet opening basically jets the washer fluid as a spread flow oscillated in the lateral direction of the vehicle. 4. The washer nozzle according to claim 2, wherein the spread jet opening has an oblong shape extending in the lateral direction of the vehicle, and has a narrowing portion for narrowing a center of the spread jet opening in the lateral direction, and wherein the spread jet opening basically jets the washer fluid as the spread flow, a center of which in a spreading direction is narrowed, the washer fluid being introduced from the feed passage. 5. The washer nozzle according to claim 2, wherein the spread flow jetted from the spread jet opening has a spread spray angle, and wherein the directional jet flow jetted from the jet opening has a jet spray angle, which has a predetermined relationship to the spread spray angle. 6. The washer nozzle according to claim 2, wherein the jet opening is displaced from the spread jet opening. 7. The washer nozzle according to claim 6, wherein the branch channel is disposed in the nozzle element, and wherein the jet opening is disposed in the nozzle body or the nozzle element, and is independent of the spread jet opening. 8. The washer nozzle according to claim 2, wherein the nozzle element includes two opposite flat faces, and wherein the spread jet opening is disposed on one flat face of the nozzle element, and the jet opening is disposed on the other flat face of the nozzle element. 9. The washer nozzle according to claim 2, wherein the branch channel has a narrowed portion with a predetermined shape for connecting to the jet opening. 10. A washer nozzle for supplying washer fluid to a windshield glass of a vehicle, the washer nozzle comprising: a nozzle body mounted on the vehicle and having a feed passage for introducing the washer fluid; a nozzle element integrally assembled in the nozzle body so as to connect to the feed passage, and having a spread jet opening for basically jetting the washer fluid as a spread flow, which spreads in a lateral direction of the vehicle, the washer fluid being introduced from the feed passage; and a jet opening for supplementally and intensively jetting part of the washer fluid as a directional jet flow, which is different from the spread flow, the washer fluid being introduced from the feed passage, wherein the spread flow has a distribution of quantity of the washer fluid such that the quantity of the washer fluid at both ends of the spread flow jetted from the spread jet opening is larger than that in a center of the spread flow, and wherein the jet flow is jetted from the jet opening toward the center of the spread flow. 11. The washer nozzle according to claim 10, wherein the nozzle element includes an oscillation chamber for self-oscillating a mainstream of the washer fluid introduced from the feed passage, and wherein the spread jet opening basically jets the washer fluid as a spread flow oscillated in the lateral direction of the vehicle. 12. The washer nozzle according to claim 10, wherein the spread jet opening has an oblong shape extending in a lateral direction of the vehicle, and has a narrowing portion for narrowing a center of the spread jet opening in a vertical direction, and wherein the spread jet opening basically jets the washer fluid as a spread flow, a center of which is narrowed in a spreading direction, the washer fluid being introduced from the feed passage. 13. A washer apparatus suitably used for a vehicle comprising the washer nozzle according to claim 2. 14. A washer nozzle for supplying washer fluid to a windshield glass of a vehicle, the washer nozzle comprising: a nozzle body mounted on the vehicle and having a feed passage for introducing the washer fluid; a nozzle element integrally assembled in the nozzle body so as to connect to the feed passage, and having a spread jet opening for basically jetting the washer fluid as a spread flow, which spreads in a lateral direction of the vehicle, the washer fluid being introduced from the feed passage; a branch channel for introducing part of the washer fluid fed from the feed passage; and a jet opening connecting to the branch channel for supplementally and intensively jetting the washer fluid as a directional jet flow, which is different from the spread flow basically jetted from the spread jet opening, the washer fluid being introduced from the branch channel, wherein the nozzle element includes two opposite flat faces, and the spread jet opening is located on one flat face of the nozzle element, and the jet opening is located on the other flat face of the nozzle element. 15.
