Abstract:
1. An accelerator pedal apparatus comprising: a pedal arm being interlocked with an accelerator pedal and having a contact portion; a housing to rotatably support the pedal arm between a rest position and a maximum depression position around a first rotation axis line; a return spring to return the pedal arm toward the rest position; and a means for adding reaction force which includes a drive source having a drive shaft arranged at the housing and a means for rotation being rotated around a second rotation axis line in the same direction as the pedal arm in a state of being contacted detachably to the contact portion of the pedal arm and in which the means for rotation adds reaction force in the direction to return the pedal arm to the rest position with rotational drive force of the drive source by rotating the drive shaft of the drive source, a first distance from a contact position of the means for rotation with the contact portion to the first rotation axis line being formed longer than a second distance from the contact position of the means for rotation with the contact portion to the second rotation axis line, the means for rotation is directly connected to the drive shaft integrally rotated coaxially to the second rotation axis line, and is formed to define a contact section contacted detachably to the contact portion of the pedal arm in the circumference of the means for rotation, the contact section includes a cam profile shape which causes displacement so that the contact portion is displaced to be closer to the second rotation axis line while being contacted to the contact section at the circumference of the means for rotation when the pedal arm is rotated toward the maximum depression position and so that the contact portion is displaced to be farther from the second rotation axis line while being contacted to the contact section when the pedal arm is rotated toward the rest position at the circumference of the means for rotation, wherein the contact section of the means for rotation is formed so that arm length from the second rotation axis line to a normal line at a position to which the contact portion contacts varies in a rotation range between the rest position and the maximum depression position.
