PROBLEM TO BE SOLVED: To inhibit influence of frictional heat to an actuator for a brake device.SOLUTION: A brake device actuator 100 includes: a piston 1 which is pressed against a frictional force generating part 102 to generate a frictional force; an actuator body 10 which moves the piston 1; and a plate member 50 which is disposed between the actuator body 10 and the frictional force generating part 102 and faces the frictional force generating part 102. The actuator body 10 has: a housing 20 attached to the plate member 50; an electric motor 25 attached to the housing 20; and a linear motion mechanism 30 which is housed in the housing 20 and causes the piston 1 to linearly move by rotation of the electric motor 25. The piston 1 is pressed against the frictional force generating part 102 through a passing hole 50A formed at the plate member 50.SELECTED DRAWING: Figure 2
【課題】ブレーキ装置用アクチュエータへの摩擦熱の影響を抑制する。【解決手段】ブレーキ装置用アクチュエータ100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1と、ピストン1を移動させるアクチュエータ本体10と、アクチュエータ本体10と摩擦力発生部102との間に配置され摩擦力発生部102に対峙する板部材50と、を備え、アクチュエータ本体10は、板部材50に取り付けられるハウジング20と、ハウジング20に取り付けられる電動モータ25と、ハウジング20に収容され電動モータ25の回転によってピストン1を直線運動させる直動機構30と、を有し、ピストン1は、板部材50に形成される通過孔50Aを通じて摩擦力発生部102に押し付けられる。【選択図】図2
