Accelerator apparatus

An accelerator apparatus for a vehicle, comprising:

• an accelerator pedal that is adapted to be depressed in a depressing direction by a driver of the vehicle;
• a support member that is adapted to be installed to the vehicle and rotatably supports the accelerator pedal, wherein:
• the support member includes a limiting portion that limits rotation of the accelerator pedal in an opposite direction, which is opposite from the depressing direction, when a contacting portion of the accelerator pedal contacts the limiting portion;
• and
• the limiting portion forms a gap between the contacting portion and the limiting portion in a state where the accelerator pedal is rotated in the depressing direction;
• an urging member that urges the accelerator pedal in the opposite direction, which is opposite from the depressing direction;
• a rotational position sensor that senses a rotational position of the accelerator pedal;
• and
• a cover member that is provided to one of the support member and the accelerator pedal and covers the gap at any rotational position of the accelerator pedal within a rotatable range of the accelerator pedal, wherein:
• the accelerator pedal includes at least one groove that extends from an opposed surface of the contacting portion, which is opposed to the limiting portion, along the accelerator pedal in a direction opposite from the limiting portion;
• and
• at least an end part of the at least one groove, which is opposite from the limiting portion, is exposed from the cover member at any rotational position of the accelerator pedal within the rotatable range of the accelerator pedal.
