Claims

[Scope of utility model registration request]

An electromagnetic servo brake device for a motor vehicle that generates control hydraulic pressure in a brake mask cylinder by boosting the pedal force applied to the brake pedal using electromagnetic means, the device being provided between the piston of the brake mask cylinder and the brake pedal,
It includes a pedal force transmission member that transmits pedal force to the brake mask cylinder, and the electromagnetic means includes a plunger made of a magnetic material fixed to the pedal force transmission member, and a plunger provided around the plunger, and the electromagnetic means is configured to move the plunger when the brake pedal is depressed. a magnet body provided with a plunger movement space for allowing movement of the brake pedal toward the mask cylinder; An electromagnetic servo brake for an automobile, comprising a split core that can move in the same direction as the plunger when the plunger moves toward the mask cylinder side by pressing the plunger.
