Abstract

A vibration actuator comprises a stator, rollers which are respectively supported by the stator and share one rotating shaft, a connection pin for connecting the rollers to each other, a vibrating means which is connected to the stator and generates elliptic or circular motion at the contact portions between the stator and the rollers by vibrating the stator so as to rotate the rollers, and a preloading means one end of which is connected to the connection pin at the intermediate part of the rollers and pull the connection pin toward the stator thereby pressurizing the rollers against the stator.
