  • Patent number: 8820810
    Abstract: An acceleration pedal is arranged on one side, in a vehicle width direction, of a steering column cover covering a steering column so as to move forward or slant forward through a press operation of a press face thereof. A guide face is provided at a specified portion of a lower face of the steering column cover which is positioned in front of a lower-face rear end portion in a steering-shaft axis direction and on an acceleration-pedal-arrangement side, wherein the guide face is configured to project downward below an extension line extending from the lower-face rear end portion in the steering-shaft axis direction and extend forward. Accordingly, a passenger's foot can be properly restrained from moving, in the vehicle width direction, off the pedal in a vehicle head-on collision, ensuring an appropriate ingress-and-egress performance of a passenger.
