The present invention relates to a brake pedal apparatus of a vehicle, and is to mainly provide a brake pedal apparatus configured for a driver to select and adjust a braking control sense (pedal stroke & vehicle deceleration) felt by a pedal stroke with respect to vehicle deceleration of a braking sense through a simple operation. To achieve the object, a brake pedal apparatus with a variable pedal ratio comprises: a pedal shaft which is installed on a pedal plate to rotate; a brake pedal which is coupled integrally to the pedal shaft and rotates the pedal shaft while rotating about the pedal shaft as a hinge shaft at the time of a driver′s operation; a slider which rotates integrally with the pedal shaft and is coupled to move in an axial direction; a driving device which moves the slider in the axial direction in accordance with the driver′s operation; an adjustment rod which is fixed and installed to the slider and is obliquely disposed to be farther from the pedal shaft as going in the axial direction of the pedal shaft; and a transfer shaft which is coupled to the adjustment rod to move in the axial direction and, an end portion of which is coupled to a dual brake valve to operate the dual brake valve at the time of up and down movement according to the brake pedal operation, wherein the pedal ratio is adjusted while the adjustment rod moves integrally at the time of movement in the axial direction of the slider in a state where the transfer shaft is coupled to the dual brake valve. |
