前記減速機構は、前記モータのロータに連結された偏心軸と、該偏心軸に回転可能に取付けられ、互いに一体回転する入力側外歯及び出力側外歯を有する外歯車部材と、前記入力側外歯に噛合う内歯を有する固定リングギヤと、前記出力側外歯に噛合い、前記変換機構を駆動するリングギヤとを備え、前記入力側外歯及び前記出力側外歯と前記固定リングギヤ及び前記リングギヤとの少なくとも一方の歯面は、歯すじに向って歯厚が変化していることを特徴とする電動ディスクブレーキ。 An electric motor, a reduction mechanism that decelerates the rotation of the rotor of the electric motor, and a conversion mechanism that converts the rotation of the reduction mechanism into a linear motion, and the braking mechanism presses the brake pad against the disk rotor by the conversion mechanism. In electric disc brakes that generate
The speed reduction mechanism includes an eccentric shaft coupled to the rotor of the motor, an external gear member rotatably attached to the eccentric shaft and having input-side external teeth and output-side external teeth that rotate integrally with each other, and the input side A fixed ring gear having internal teeth meshing with external teeth; and a ring gear meshing with the output side external teeth and driving the conversion mechanism, the input side external teeth, the output side external teeth, the fixed ring gear, and the At least one of the tooth surfaces of the ring gear, an electric disk brake, characterized in that the tooth thickness towards the tooth trace is changing.
