Patent ID: 7553212

Claim:
An automobile model comprising: a pair of left and right driven wheels which are independently driven by different driving sources; a pair of left and right steered wheels; and a steered wheel-supporting mechanism which supports the steered wheels such that each steered wheel is adapted to turn around a predetermined steering axis and such that the steered wheels are adapted to turn only in the same direction in association with each other, wherein the predetermined steering axis is fixedly inclined with respect to a vertical direction such that an upper portion of the steering axis is located rearward of a lower portion of the steering axis in a traveling direction, and wherein the steered wheel-supporting mechanism is further configured such that, when a speed difference is generated between the driven wheels to turn the automobile model in a turning direction, the steered wheels are naturally steered in the turning direction without any additional steering driving force by a reaction force received from a ground-contact surface.
