PROBLEM TO BE SOLVED: To suppress rattling of an output rod by reducing the wear amount of slide bearing means.SOLUTION: A toe control actuator 18 that reduces rotary driving force of a motor 42 by a planetary gear mechanism 44 and transmits the driving force to a carrier, and also converts rotary motion of the carrier into reciprocal linear motion of an output rod 32 by a feed screw mechanism 48 includes: a first slide bearing 108 which is arranged in a slide region of a second housing 30b and the output rod 32; and pressurization means 200 which pressurizes the second housing 30b. The pressurization means 200 has a groove part 202 formed at the second housing 30b a leaf spring which presses the groove part 202 to pressurize the second housing 30b in a radial direction, and a fixation member 208 which fixes the leaf spring to the output rod 32.

    【課題】スライド軸受手段の磨耗量を低減して出力ロッドのガタツキを抑制すること。【解決手段】モータ42の回転駆動力を遊星歯車機構44で減速してキャリアに伝達し、キャリアの回転運動を送りねじ機構48によって出力ロッド32の往復直線運動に変換するトーコントロールアクチュエータ18において、第2ハウジング30bと出力ロッド32との摺動部位に配設される第1スライドベアリング108と、第2ハウジング30bに対して与圧を付与する与圧付与手段200とを備え、与圧付与手段200は、第2ハウジング30bに形成される溝部202と、溝部202を押圧して第2ハウジング30bの径方向に与圧を付与する板ばねと、出力ロッド32に対して板ばねを固定する固定部材208を有する。【選択図】図3
