PURPOSE: A geometry bush for the lower arm of a vehicle is provided to improve the service life of an arm bush by preventing a rubber member from cracking when a repeated load is applied by insert-injecting a reinforcement member into a void part. CONSTITUTION: A geometry bush for the lower arm of a vehicle comprises external iron(110), a core(120), a rubber member, a void part(140), and a reinforcement member(150). The core is equipped inside the external iron. The core is equipped with a through-hole(125). The rubber member is interposed between the core and the external iron. The void part is alternately formed with the rubber member between the core and the external iron. The reinforcement member is equipped on the inner side of the void part. The reinforcement member is made of steel with a closed sectional shape. The reinforcement member is insert-injected when curing-molding the rubber member.
