A reaction force generating unit is provided inside the casing, and the reaction force generating unit is configured to generate a reaction force with respect to the brake pedal in accordance with an amount of change in the posture of the brake pedal during the brake operation, and to cause the brake pedal to return to a reference position when the brake operation is released. A sensor unit is provided outside the casing, to detect an amount of change in the posture of the brake pedal, and a sensor protector is provided at the casing in a position away from the brake pedal, to cover at least a part of the sensor unit.

Abstract: A pedal device includes a pedal and a reaction force generation mechanism. The reaction force generation mechanism includes a resilient device and a first holder. The first holder contacts the resilient device from one side, which is a side where the pedal is placed. The first holder has a primary disengagement stopper. The reaction force generation mechanism includes a second holder that contacts the resilient device from another side, which is opposite to the one side. The second holder has a secondary disengagement stopper. In a non-depressed state of the pedal, the pedal limits movement of the first holder toward the one side. When the pedal no longer limits and thus releases the movement of the first holder, the secondary disengagement stopper limits the movement of the first holder relative to the second holder beyond a predetermined limit toward the one side.

Furthermore, the force applied from the pedal at the time of rotating the pedal moves the second guide portion to slide relative to a third guide portion of a guide member in the vehicle front-rear direction, resulting in deformation of a second resilient member.
