PURPOSE: A structure for preventing a bush of a bus air suspension from being worn out is provided to absorb the external force applied from a lower radius rod by converting the force to rotation force, thereby preventing the abrasion of the bush and increasing the durability of the bush. CONSTITUTION: A structure for preventing the bush abrasion of a bus air suspension includes a bush(6) mounted to a coupling portion between a lower radius rod(3) and a suspension supporter for converting the external force applied to the coupling portion into rotation force to distribute the external force, wherein the bush includes a pin bolt(6a) formed with a grease groove(6a') to be introduced with grease, an inner element(6b) inserted into the pin bolt, an outer element(6c) surrounding the inner element and pressed by the lower radius rod, and a distribution element(10) provided between the pin bolt and the outer element for distributing the external force applied by the lower radius rod and generating rotation force.
