Abstract
Disclosed herein are a steering rack and a method of manufacturing the same. The steering rack includes a body part having both ends, each of which is connectable to a respective wheel and extending in a width direction of a vehicle body, and a threaded part provided on one side of the body part and having screw gear teeth configured to be engageable with a ball nut configured to be rotatable by power of a motor by means of a ball. The screw gear teeth may be divided into a first area relatively adjacent to a center of the threaded part and a second area relatively adjacent to both ends of the threaded part, and an over ball diameter of the first area is different from an over ball diameter of the second area.
