An anti-wind eccentric umbrella, comprising a shaft (3), a framework, an upper ring (1), a lower ring (2) and a canopy (10), in which the framework is composed of ribs (6), stretchers (7) and a main frame (5). The two ends on one side of a main frame (5) that is cross-hinged by a first main brace (501) and a second main brace (502) through a main frame hinge axis (503) are respectively hinged with the upper ring (1) and the lower ring (2). The anti-wind eccentric umbrella comprises a rib vacant position and the rib vacant position and the ribs are distributed in 360°. The main frame is on the rib (6) vacant position, the top notch (301) is hinged with an auxiliary rib (9), the runner (4) is hinged with an auxiliary stretcher (8) and the auxiliary stretcher (8) is at the rib vacant position at the outer side of that occupied by the main frame (5). The present invention solves the structural problem and poor anti-wind stability that are present in the prior art.
