Patent attributes
An accelerator pedal device having a pedal arm working in conjunction with an accelerating pedal, a housing to rotatably support the pedal arm around a prescribed pivot axis line between a rest position and a maximum applied position, a hysteresis generation mechanism that comes in contact with the vicinity of an upper end of the pedal arm to generate hysteresis in a pedal force of the accelerator pedal, and an active control mechanism to push back the pedal arm toward the rest position under prescribed conditions between the pivot axis line and the hysteresis generation mechanism. The active control mechanism includes a drive source provided in the housing, and a return lever that is rotated in the same direction as the direction of the swinging of the pedal arm in conjunction with the drive source and is detachably engaged with the vicinity of the upper end of the pedal arm.
