Abstract: A buffering structure for wheels comprises at least a linking plate, a spindle, two concentric rigid hollow ferrules or up, and a kind of firm buffer material. When applying this invention, an outer end of the linking plate is hitched on the wheel shaft while the spindle is connected with a shaft carrier under a pushcart's deck. Therefore, in the event a wheel is conflicting with a curb for example, the impact of the wheel is imparted to the through hole in the outer end of the linking plate via the shaft, such that the outer end is driven to rotate surrounding the spindle to thereby convert the impact into a rotation force, and meanwhile, the buffer material stuffed inside and outside the smaller rigid ferrule is interacted with the rotating smaller ferrule and deformed to absorb the rotation force to alleviate that impact.
