Abstract: A pedal device mounted on a vehicle includes a housing, a pedal pad, and a reaction force generation mechanism. The housing is mounted on a vehicle body. The pedal pad is provided to be rotatable with respect to the housing. The reaction force generation mechanism is configured to include a plurality of resilient members each having a predetermined leaf spring. The reaction force generation mechanism is arranged in a space on the side opposite to a surface stepped on by a driver in the pedal pad to generate a reaction force against a pedaling force applied to the pedal pad by the driver.

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.

Abstract: An output gear includes a fixing portion, which is joined to a surface-processed portion of an output shaft, and a connecting portion that connects between a toothed portion of the output gear and the fixing portion. A length, which is measured from a center of a boundary surface between the connecting portion and the fixing portion in an axial direction of an axis of the output shaft to one end part of a joint between the surface-processed portion and the fixing portion on a linkage mechanism side along the joint, is indicated by L1. A length, which is measured from the center of the boundary surface to an opposite end part of the joint that is opposite to the linkage mechanism in the axial direction, is indicated by L2. A relationship of L1>L2 is satisfied.
