Abstract:
1. An electric booster, comprising: an electric motor adapted to be actuated in response to an actuation instruction; a rotation-linear motion converting mechanism operable to convert a rotation of the electric motor into a linear motion and transmit it to an output member, the output member being capable of pushing a piston of a master cylinder to generate a brake fluid pressure in a pressure chamber in the master cylinder; an ECU casing containing a board for controlling the electric motor, the ECU casing being formed integrally with a motor casing of the electric motor, the ECU casing being coupled with the motor casing so as to be offset in one direction in a plane perpendicular to a plane containing an axis of the master cylinder; and a connector for supplying at least a power source to the board, the connector being provided at an end of the ECU casing on the side where the ECU casing is offset, or an opposite side from the side where the ECU casing is offset.
