摘要： A power steering system to reduce the moment of inertia of the torque limiter and to accurately determine pressing force by a forcing member is provided. The torque limiter of the system has a basic structure in which a substantially-cylindrical rotating member (23) which is rotatable together with one of the output shaft (20, 120) and the input shaft (21); and a rotated member (24, 124, 324, 424) which is rotatable together with the other of the output shaft and the input shaft, and which is forced toward the rotating member side by a forcing member (26) supported by the rotating member. Typically, the rotating member is a substantially-cylindrical limiter cover with a bottom, and the rotated member is a limiter plate contained in the limiter cover. The forcing member may be supported by a concave portion formed in an inner-peripheral area of the limiter cover, or may be supported by a projecting portion which is formed by deforming the cylindrical portion of the limiter cover toward the inside. In the above basic structure, the rotated member may separately comprise a cylindrical portion (124A, 324A, 424A), on the inner-peripheral surface of which plural splines are formed in parallel with its axial direction, these splines being engaged with the splines formed in the outer-peripheral surface of the other of the output shaft and the input shaft; and a flange portion (124B), which is forced toward the rotating member side, by which the flange portion functions as a friction clutch. In this structure, efficiency of forming the limiter plate can be improved.

摘要： A power steering system is provided, the torque limiter (522) of which has a structure having a superior power-transmitting efficiency, and by which the sliding torque can be easily and accurately determined. The torque limiter comprises a cylindrical case (500); a base (540) combined with the case; a rotated member (324) which is rotatable together with the input shaft of the steering unit; and a forcing member, provided between the base and the rotated member, for generating a pressing force due to friction, wherein the torque limiter is combined with the driving unit by pressing and inserting the output shaft of the driving unit into the axial hole of the base.
