A vibration device includes a base, a movable bench elastically supported with respect to the base, a first horizontal excitation unit that vibrates the movable bench in a first horizontal direction, a second horizontal excitation unit that vibrates the movable bench in a second horizontal direction that crosses the first horizontal direction, a vertical excitation unit that vibrates the movable bench in a vertical direction, and first and second middle benches between the base and the movable bench, wherein first to third plate-like spring members elastically connect the base, the first and second middle benches, and the movable bench sequentially in the first horizontal direction, the second horizontal direction, and the vertical direction.

An article sorting and conveying device that conveys articles by the vibrations of a movable body provided through an elastic support unit, includes a first vibration unit that imparts a periodic vibration force to the movable body in a direction inclined from a vertical direction; a second vibration unit that imparts a periodic vibration force in a direction crossing the periodic vibration force by the first vibration unit; and a vibration control unit that causes a periodic vibration force imparted by each vibration unit to have a phase difference and occur simultaneously at the same frequency, and that creates an elliptical vibration trajectory in the movable body. The articles are sorted and conveyed on the movable body by setting the vibration trajectory of the movable body by the vibration control unit such that articles having a different coefficient of friction are conveyed in different directions.
