PROBLEM TO BE SOLVED: To reduce energy loss of an actuator for a brake gear.SOLUTION: An actuator 200 for a brake gear includes: a piston 110 which is pressed to a friction force generating part 102 to generate a friction force; a ball screw 31 to which the piston 110 is connected; a ball nut 35 which is threadedly engaged with the ball screw 31; an electric motor 25 which rotates the ball nut 35 and causes the ball screw 31 to linearly move. The piston 10 is attached to the ball screw 31 so as to move relative to the ball screw 31 in an axial direction and a radial direction of the ball screw 31.SELECTED DRAWING: Figure 3

    【課題】ブレーキ装置用アクチュエータのエネルギロスを低減する。【解決手段】ブレーキ装置用アクチュエータ200は、摩擦力発生部102に押し付けられて摩擦力を発生させるピストン110と、ピストン110が連結されるボールねじ31と、ボールねじ31に螺合するボールナット35と、ボールナット35を回転させてボールねじ31を直線運動させる電動モータ25と、ピを備え、ピストン10は、ボールねじ31に対して、ボールねじ31の軸方向及び径方向に相対移動可能に取り付けられる。【選択図】図3
