A brake actuator includes: a housing; an electric motor with a hollow motor shaft rotating; a rotating shaft disposed inside the motor shaft to be coaxial therewith; a piston with a rear end disposed inside the motor shaft and a front end engaged with the friction member; a speed reduction mechanism decelerating rotation transmitted from the motor shaft and transmitting the rotation to the rotating shaft; and a motion conversion mechanism converting a rotating motion of the rotating shaft into an advancing/retracting motion of the piston. The motor shaft is rotatably supported by the housing at an outer peripheral surface thereof, and the rotating shaft is rotatably supported by an inner peripheral surface of the motor shaft via rollers at an outer peripheral surface thereof as well as by the housing via a thrust bearing at a rear end of the rotating shaft.
