Patent ID: 8438945

Claim:
An electronic organ type accelerator pedal apparatus, comprising: a pedal housing that is fixed to a dash panel under a driver's seat, and has a body provided with a pedal arm receiving space that is open to one side, a rotational shaft protrusion that protrudes from an inner side of the pedal arm receiving space and a carrier fitting hole that is open upward from the pedal arm receiving space; a pedal arm that is fitted on the rotational shaft protrusion to be rotatable in the pedal arm receiving space, has one end that receives elastic force of a spring member supported by the body, and a sensor fitting protrusion that integrally protrudes from a side of the end that receives the elastic force of the spring member; a carrier that is combined with the pedal arm through the carrier fitting hole and has a carrier protrusion at a lower portion of the carrier, wherein the carrier protrusion protrudes in a longitudinal direction of the body and is positioned in the pedal arm receiving space; a housing cover that is combined with the body to cover the open side of the body; a pedal sensor that has a sensor lever connected with the sensor fitting protrusion and is fastened to a side of the housing cover; a hinged portion that is integrally formed with the body, fixed to a floor panel under the driver's seat, a hinge fitting groove that is open upward and to a side; and a pad portion that has a hinge portion integrally formed with one end of the pad portion combined with the carrier and fitted in the hinge fitting groove and directly engaged with the hinge fitting groove; wherein a protrusion fitting hole is formed in the bottom of the hinge fitting groove, wherein a hinge protrusion that is fitted in the protrusion fitting hole but not directly engaged with the hinge fitting groove when the hinge portion is fitted in the hinge fitting groove integrally protrudes down from the bottom of the hinge portion, wherein the hinge protrusion is formed in a substantially triangular cross section along a longitudinal direction of the hinge fitting groove, and wherein the substantially triangular cross section has: a declined surface that gradually protrudes down from the bottom of the hinge portion along a longitudinal direction of the substantially triangular cross section and is coupled with the hinge fitting groove; and a vertical surface that connects the end of the declined surface with the bottom of the hinge portion and is coupled to the protrusion fitting hole so as to prevent the hinge portion disassembling from the hinge fitting groove by being engaged with the protrusion fitting hole.
