An electric booster in which a rotation of an electric motor is converted into linear motion and transmitted to an output member by a rotation-linear motion mechanism. The output member pushes a piston of a master cylinder to generate brake fluid pressure in a pressure chamber in the master cylinder. An ECU casing containing boards is coupled to the top of a motor casing constituting the electric motor. The ECU casing is offset in one direction in a plane perpendicular to a plane containing an axis of the master cylinder. A male connector is provided at a side surface of the ECU casing on the opposite side from the offset direction side, and a space between the male connector and an interference area of the ECU casing is utilized as a space for attachment/detachment of the male connector.
An electric booster, comprising:
An electric booster configured to transmit a driving force of an electric motor to an output member by a transmission mechanism, and generate a brake fluid pressure in a pressure chamber in a master cylinder by a thrust force of the output member, the electric booster comprising:
An electric booster configured to drive an electric motor according to a driving instruction, convert a rotation of the electric motor into a linear motion by a rotation-linear motion conversion mechanism to transmit the linear motion to an output member, and thrust a piston of a master cylinder by the output member to generate a brake fluid pressure in a pressure chamber in the master cylinder,
