Patent number: 11485338Abstract: This electric braking device is provided with: an electric motor MTR that, in accordance with an operation amount Bpa of a braking operation member BP, generates a pressing force Fba, being a force pressing a friction member MSB against a rotary member KTB that rotates integrally with a wheel WHL of the vehicle; and a circuit board KBN to which a processor MPR and a bridge circuit BRG are mounted. The device is further provided with a rotation angle sensor MKA for detecting the rotation angle Mka of the electric motor, and drives the electric motor MTR on the basis of the rotation angle Mka. An end face Mmk of the rotation angle sensor MKA is fixed so as to be in contact with the circuit board KBN. The device is further provided with a pressing force sensor FBA for detecting the pressing force Fba, and drives the electric motor MTR on the basis of the pressing force Fba. An end face Mfb of the pressing force sensor FBA is fixed so as to be in contact with the circuit board KBN.Type: GrantFiled: July 23, 2020Date of Patent: November 1, 2022Assignee: ADVICS CO., LTD.Inventors: Yoshiyuki Yasui, Tomonori Katsuyama
