Beschreibung
Zusammenfassung:	A three-dimensional drive device of this invention comprises: a hollow shaft; a first motor rotating the hollow shaft; a first spur gear having a central axis common to a central axis of the hollow shaft, arranged in a center of the hollow shaft; a second motor rotating the first spur gear; a bevel gear meshing with the first spur gear, arranged within the hollow shaft; and a second spur gear meshing with the bevel gear, arranged within the hollow shaft, and having an axis of rotation orthogonal to the central axis of the hollow shaft, the bevel gear and the second spur gear being to turn upon moving in the circumferential direction of the hollow shaft along with rotation of the hollow shaft, and the central axis of the hollow shaft and the axis of rotation of the second spur gear being orthogonal to each other.
