PROBLEM TO BE SOLVED: To stably maintain spring performance of a pressurization spring by reducing a rise in temperature of a carrier.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 78, and also converts rotary motion of the carrier 78 into reciprocal linear motion of an output rod 32 by a feed screw mechanism 48 includes: an elastic coupling 46 which is arranged between the feed screw mechanism 48 and carrier 78, and generates resilient force along an axis L; and a pinion 84 which engages a ring gear 74 and a sun gear 76. The carrier 78 has a first end face 79 opposed to an elastic coupling 46 and a second end face 81 facing the side of the pinion 84 on the opposite side from the first end face 79, and the first end face 79 is provided with a recessed part 83 which is hollowed to the side of the second end face 81.

    【課題】キャリアの温度上昇を低減し、与圧ばねのばね性能を安定して維持すること。【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78に伝達し、キャリア78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、送りねじ機構48とキャリア78との間に配置されて軸線L方向の弾発力を発生する弾性カップリング46と、リングギヤ74及びサンギヤ76にそれぞれ噛合するピニオン84とを備え、キャリア78は、弾性カップリング46に対向する第1端面79と、第1端面79の反対側でピニオン84側に臨む第2端面81とを有し、第1端面79には、第2端面81側に窪む凹部83が設けられる。【選択図】図3
