Abstract
A pedal device which can alleviate fatigue of a driver's ankle due to frequent acceleration by varying the amount of reaction force applied when the driver presses and releases a pedal by adjusting a pre-compression force against a return spring disposed at a hinged portion of a pedal arm and adjusting a friction force on a pivot end of the pedal arm. The pedal device includes a housing fixed to a car body, an arm hinged to the housing, an elastic member disposed at the hinged portion between the housing and the pedal arm, a pedal effort adjusting unit disposed at the pedal arm and pressing an end of the elastic member, and a hysteresis adjusting unit movably disposed at the housing to press a pivot end of the pedal arm and adjusting the amount of change in stroke-to-pedal effort when the pedal arm operates.
