Abstract: An electric braking device generates a braking force at a wheel via application of a pressing force by a piston by linear motion of the piston in response to the transmission of a forward-direction rotational torque from an electric motor to a linear motion conversion mechanism. The electric braking device is provided with a one-way clutch that cuts off the transmission of a rotational torque between the electric motor and the linear motion conversion mechanism when applied with a rotational torque in a direction opposite to the forward direction and having a magnitude equal to or greater than a predetermined value.

Abstract: In a brake fluid pressure control apparatus, a sensing device is integrally fixed to a master piston. The sensing device including the body to be sensed, which may include a magnet, and a sensing body, which may include a sensor. The sensing bodying sensing an axial position of the master piston without relative movement, that is, without providing play. This arrangement improves the sensing precision of the sensing device. Since it is not necessary to provide a member separate from the master piston in order to retain the body to be sensed, it is possible to achieve downsizing of the brake fluid pressure control apparatus.

Abstract: A brake fluid pressure supply unit includes a fluid pressure generation device in which a piston that slides in a cylinder is driven by an electric motor to generate fluid pressure in a fluid pressure chamber formed in the cylinder; and a housing in which a fluid path connected to the fluid pressure chamber is formed. The electric motor and the cylinder are both attached to the housing. The electric motor is positioned more on upper side of the brake fluid pressure supply unit than the cylinder in a vertical direction. Thus, even if fluid leaks from the cylinder, the fluid having leaked can be prevented from entering inside of the electric motor. Thus, the operation of the electric motor is not impaired, whereby the reliability of the brake fluid pressure supply unit can be improved.
