PURPOSE: A lower arm bush reduces the transfer of weight by impact, prevents or reduces an abrasion or a damage and reduces a noise, thereby enabling a pleasant running. CONSTITUTION: A lower arm bush comprises a bush body(10), a core(12) and a lower arm bracket(14). A protruded portion(13) contacts to the inner surface of the lower arm bracket(14) when a lower arm bush(15) is bent or transformed by an outer force by being protruded to the outside of the longitudinal direction of the core(12). Even when the lower arm bush(15) is elastically transformed, only the protruded portion(13) is contacted to the inner surface of the lower arm bracket(14). Thus, the transfer of weight by an impact between the lower arm bush(15) and the lower arm bracket(14) are reduced. Therefore, the abrasion, the damage and the noise of the lower arm bush(15) and the lower arm bracket(14) are reduced.
