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.
