Patent ID: 8001870

Claim:
An accelerator comprising: a housing; a bearing part fixed to the housing; an urging part fixed to the housing; an accelerator pedal that has a turning shaft supported by the bearing part and an abutting part, the turning shaft being turned forward when a depressing force is applied thereto and is turned reversely when an urging force of the urging part is applied thereto; a stopper fixed to the housing to abut against the abutting part of the accelerator pedal to limit reverse turn of the accelerator pedal, the stopper providing a totally closed position of the accelerator pedal when abutting the abutting part of the accelerator pedal; and a turning angle sensor that is disposed between the turning shaft and the housing to detect a turning angle of the accelerator pedal, wherein one of the stopper and the abutting part has a guiding surface substantially parallel to a direction in which the urging force is applied so that the stopper and the abutting part abut each other at the guiding surface when the accelerator pedal is totally closed and so that when abutted, the stopper guides the abutting part to slide along the guiding surface; wherein the turning angle detecting sensor comprises: a magnetism detecting part that is fixed to the housing and provided with two first magnetic bodies arranged side by side in a first direction, and an electromagnetic conversion device sandwiched between the two first magnetic bodies; and a magnetic field forming part that is fixed to the turning shaft so as to rotate relative to the magnetism detecting part when the turning shaft turns and provided with two second magnetic bodies, and two permanent magnets, the second magnetic bodies having flat facing portions facing each other across the magnetism detecting part in a second direction perpendicular to the first direction, and wherein the first direction is along the direction in which the urging force is applied when the accelerator pedal is in the totally closed position.
