Abstract
A vibration actuator comprises a rod-shaped vibration element including an elastic unit having plural elastic members and an electromechanical converting device with portions mounted between mutually adjacent ones of the elastic members and adapted to generate mutually different plural vibrations and a relative movement member contacting an end face of the vibration element and adapted to effect a movement relative to the vibration element. The vibration element is so formed that the cross section thereof perpendicular to the axis thereof varies along the axis.
