Abstract: A brake device for a vehicle includes: a brake pedal having a pedal portion and a lever portion that rotates about a rotation axis when the pedal portion is operated; a housing that rotatably supports the lever portion; and a plate member configured to generate a reaction force with respect to the lever portion in response to a stroke amount of the brake pedal. The plate member has a longitudinal surface defined by a side extending in a longitudinal direction of the plate member and a side extending in a width direction of the plate member. The longitudinal surface is arranged so as to face the lever portion. When the pedal portion is operated, the plate member is bent to generate the reaction force.

Abstract: A vehicle brake system includes a vehicle brake device and a hydraulic pressure generation unit. The vehicle brake device includes: a brake pedal that has a pedal portion, and a lever portion rotating about a rotation axis in response to the pedal portion being operated; a stroke sensor that outputs a signal based on a stroke amount of the brake pedal; a housing that rotatably supports the lever portion; and a reaction force generation portion that generates a reaction force applied on the lever portion based on the stroke amount. The hydraulic pressure generation unit generates a hydraulic pressure for braking a vehicle.
