Patent ID: 8596163

Claim:
A pedal unit, comprising: a pedal bracket that rotatably supports a brake pedal; a pedal stroke sensor that is provided to the pedal bracket, makes rotating displacement by receiving a deflection of the brake pedal around a pivot of the brake pedal at an input section, and detects a pedal deflection angle of the brake pedal; and a link mechanism that links the brake pedal and the input section of the pedal stroke sensor, the link mechanism amplifying a pedal deflection angle of the brake pedal and transmits to the pedal stroke sensor and transmitting to the pedal stroke sensor, wherein: the pedal stroke sensor is placed at a point of the pedal bracket, which is located away from the brake pedal, and where a pivot of the pedal stroke sensor is not aligned with the pivot of the brake pedal; the brake pedal is rotatably supported in the pedal bracket by means of a support shaft formed integrally with the brake pedal; the brake pedal and the input section of the pedal stroke sensor are located away from each other, and the link mechanism includes an output arm projecting from an outer circumferential surface of the support shaft, the output arm extending from the support shaft at a position offset from the brake pedal in an axial direction of the support shaft, an input arm radially projecting from the input section of the pedal stroke sensor, and a link member that rotatably connects a tip end of the output arm and a tip end of the input arm by using a ball joint respectively to each other, a length of the output arm and a length of the input arm being longer than a length of the link member; and both ends of the support shaft are supported by opposing walls of the pedal bracket, and the pedal stroke sensor is provided in a region between the opposing walls.
