Abstract
An object distance adjusting apparatus includes a first adjustment mechanism, a second adjustment mechanism, and a third adjustment mechanism, the first adjustment mechanism being meshed with the second adjustment mechanism, and the second adjustment mechanism being meshed with the third adjustment mechanism. Rotation of the first adjustment mechanism drives the second adjustment mechanism to rotate, and rotation of the second adjusting mechanism drives the third adjusting mechanism to rotate. A rotation axis of the third adjustment mechanism is perpendicular to both a rotation axis of the first adjustment mechanism and a rotation axis of the second adjustment mechanism. A virtual reality device including the object distance adjusting apparatus is also disclosed.
