Abstract
A testing apparatus of a steering system is provided to correctly detect load in a direction in which steering reaction force acts, the load being applied to the steering system. A tie rod connected to a rack of the steering system is connected to a steering-angle vibrating unit via a torque lever, relay links and a drive link. A front link of the drive link and a link disposed parallel to the torque lever are provided in a swingable manner. Both ends of each of the relay links are respectively connected to the torque lever and the link disposed parallel to the torque lever, and the torque lever is swingable with respect to the link in a direction in which road-surface reaction force acts. Transducers are provided at intermediate portions of the relay links, respectively. A vertically-vibrating unit is connected via the torque lever to the rack.
