Accelerator apparatus

An accelerator apparatus for a vehicle, comprising:

• a support member that is installable to a body of the vehicle;
• an accelerator pedal that is rotatably supported by the support member, wherein the accelerator pedal is rotated in a first rotational direction when the accelerator pedal is depressed by a driver of the vehicle;
• an urging member that has one end portion engaged with the support member and urges the accelerator pedal in a second rotational direction, which is opposite from the first rotational direction;
• a sensor that senses a relative rotational angle between the accelerator pedal and the support member and outputs a rotational angle signal, which indicates the relative rotational angle;
• a signal output device, from which the rotational angle signal received from the sensor is externally outputted out of the accelerator apparatus;
• a sensor holder that is engaged with the support member and integrally holds the sensor and the signal output device at a first-side portion and a second-side portion, respectively, of the sensor holder, which are spaced from each other;
• a primary engaging arrangement, through which the first-side portion of the sensor holder is engaged with the support member;
• and
• a secondary engaging arrangement, through which the second-side portion of the sensor holder is engaged with the support member, wherein:
• the secondary engaging arrangement includes at least one secondary engaging portion of the sensor holder, which is provided in the second-side portion of the sensor holder and is engaged with the support member;
• and
• a distance from an engaging point between the secondary engaging portion of the sensor holder and the support member to the sensor is longer than a distance from the engaging point between the secondary engaging portion of the sensor holder and the support member to the signal output device.
