ABSTRACT:
A driving device for adjusting an orientation of a wheel attached to a vehicle body includes: a driving unit; a lifting shaft extending along a first axis and capable of moving axially when driven by the driving unit; a suspension arm extending along a transverse direction intersecting the first axis, and having one end adapted for connection with the wheel and another end disposed in proximity to the lifting shaft; and a cam unit including at least one roller connected to one of the lifting shaft and the suspension arm, and an inclined cam face provided on the other one of the lifting shaft and the suspension arm. The roller and the inclined cam face interact with each other such that the suspension arm moves along the transverse direction.
