PURPOSE: A water withdrawal resisting assembly for reverse osmosis water purifier is provided, which is characterized in that impurities captured in reverse osmosis membrane can be removed rapidly while maintaining the internal pressure of the membrane constant even without using pressure regulation pipe with small diameter. CONSTITUTION: The water withdrawal resisting assembly for reverse osmosis water purifier comprises a cap(20) formed with a withdrawal water inlet(22); a housing(21) formed with a withdrawal water outlet(23) being assembled with the cap; a pipe bobbin(25) which is installed inside the housing; a partition(27) which comparts withdrawal water passage(26a,26b); a withdrawal water groove(28) which is formed around the outer circumferential surface of the pipe bobbin; a withdrawal water inlet hole(29) and a withdrawal water outlet hole(30) which are respectively formed on the withdrawal water groove; a filter which is installed at the withdrawal water inlet on the cap to prevent impurities from introducing into the pipe bobbin.
