PURPOSE: A power steering gear is provided to reduce the purchase costs of testing equipment and to directly install as occasion demands by moving the power steering gear and a hydraulic device leftward and rightward through the combination of a pulley and a belt. CONSTITUTION: A testing device of a power steering device(21) contains a gear rotating member(23), a hydraulic rotating member(24), a belt(26), a pulley(27) and a motor(28). The gear rotating member is installed in the power steering gear. The hydraulic rotating member is installed in a hydraulic device(22) connected with the power steering gear through a tie rod(25). The belt is combined with the gear rotating member and the hydraulic rotating member by crossing each other. The pulley rotates the belt. The motor generates driving force by interlocking with the pulley. Thereby, an expensive hydraulic device is alternated by the pulley and the belt.
