ABSTRACT:
In manufacturing a knuckle body forged or cast from light alloy of a suspension device, a large vertical height of a pair of bosses protruding downward from front and rear ends in a lower portion of the knuckle body may cause degradation in forgeability or castability of the knuckle body to hinder manufacturing, and also cause reduction in rigidity of the bosses to reduce mounting strength of a lower arm support bracket made of ferrous metal. A vertical height of the pair of bosses of the knuckle body is set to be smaller than a vertical height of the lower arm support bracket, thereby improving forgeability or castability of the knuckle body and increasing rigidity of the bosses.
