Optical forces exerted upon the endface of optical nanofiber have been carefully investigated numerically. Detailed spatial optical force distributions along the fiber axis are obtained. Dependence of optical force on fiber diameters, input modal polarizations, oblique-cut endfaces are carefully taken into considerations. It is clear now that oblique-cut fiber endface should be responsible for sideways deflection of nanofiber.
