Abstract
A motion device includes an orbital element, and a moving element into which the orbital element is inserted, the moving element guided so as to be able to reciprocate in a longitudinal direction of the orbital element, wherein at ends of the moving element, cylindrical protrusions into which the orbital element is inserted are formed and protrude in the longitudinal direction of the orbital element so as to be pivotally supportable on bearings, and total size around the orbital element in a direction perpendicular to the longitudinal direction of the protrusions is smaller than that of the moving element.
