摘要： The invention relates to a power steering system (1) including an electric motor (20) for generating a steering force in response to an command value, and a controller (17) for generating the command value to the electric motor (20). Here, the controller (17) generates the command value in correspondence with steering state of wheels (8a, 8b), thereby controlling torque or rotation number of the electric motor (20).

摘要： In a mechanism for converting rotary motion into linear motion, a large thrust can be generated by arranging a revolving roller (21-24; 121-24) provided on an outer peripheral surface thereof with a roller groove (21b-24b), which makes a round, on a holder (3) so as to make the revolving roller (21-24; 121-124) mesh with a rack thread (1a) of a centrally positioned rack rod (1), revolving the revolving roller (21-24; 121-124) around the rack rod (1) with a motor (5) to translate the rack rod (1) to make a force transmission part linear, and high efficiency is realized by having the rack rod (1) making rolling contact circumferentially and eliminating slippage thereof in an axial direction.
