Abstract
Disclosed is a wheel assembly including a driving rotation part being rotatable about a driving rotation axis that is a rotation axis that extends in one direction, and a variable rotation part being rotatable about a variable rotation axis that is an imaginary rotation axis, of which a relative location to the driving rotation axis is variable, and being movable relative to the driving rotation part along a direction that is not parallel to the one direction, wherein a relative location of the variable rotation axis to the driving rotation axis is variable when the variable rotation part is moved relative to the driving rotation part.
