PURPOSE: To perform regular and uniform scattering of a fluid in a wide range, in a scattering element utilized in the window washer nozzle for a car, by providing a deflection wall for deflecting a jet stream, a distribution wall for distributing the jet stream and a turning wall for turning the distributed stream to allow the same to collide with the jet stream to a jet stream flow passage.
CONSTITUTION: A deflection wall for sucking and deflecting a jet stream F by the mutual action of said jet stream F, a distributing wall 43 for distributing the jet stream F into distributed streams F3, F4 and a turning wall 42 for turning the distributed streams F3, F4 to allow both of them to collide with the jet stream F and pushing away said jet stream F to the direction opposite to the deflecting direction thereof are provided to a jet stream flow passage 4. By this mechanism, even if a feedback flow passage is not provided, the regular and uniform scattering of a fluid is enabled in a wide range.
