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 brake device includes: a brake pedal including a pedal and a lever that rotates about a rotation axis when the pedal is operated; a housing that rotatably supports the lever; a reaction force generator that generates a reaction force to the lever in accordance with a stroke amount of the brake pedal by receiving a force from the lever when the brake pedal is operated; a deformation member including a deformation portion that is deformed by a force received from the lever when the brake pedal is operated in a state where the reaction force generated by the reaction force generator is generated; and a stroke sensor that outputs a signal corresponding to the stroke amount and outputs a value indicating that operation of the brake pedal is abnormal and instructing execution of control for stopping a vehicle when the deformation portion is deformed.
