Abstract
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 which is rotatable together with one of the output shaft and the input shaft; and a rotated member 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 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, on the inner-peripheral surface of which plural splines are formed in parallel with its axial direction, these splines being engaged with…
