Abstract
Official abstract text for this publication.
A vibration actuator that is easy to manufacture and has good driving performance, and a lens-barrel and a camera provided with the same. The vibration actuator is provided with an oscillator that generates oscillations; and a relative movement member that is pressure contacts the oscillator, and moves relative to the oscillator due to the oscillation. Either a contact face of the oscillator with respect to the relative movement member or a contact face of the relative movement member with respect to the oscillator is a thermosetting resin film that is formed of polyamide-imide resin and fluororesin, and the other contact face is an anodic oxide film.
First claim
Opening claim text (preview).
1 . A vibration actuator comprising: an oscillator configured to generate oscillations, and a relative movement member which is in pressure contact with the oscillator configured to relatively move with respect to the oscillator due to the oscillations, wherein of a contact face of the oscillator with respect to the relative movement member and a contact face of the relative movement member with respect to the oscillator at least one is a thermosetting resin film composed of a polyamide-imide resin and a fluororesin and the other is an anodic oxide film.
