VIBRATION WAVE DRIVING APPARATUS AND IMAGE PICKUP APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18496261 titled 'VIBRATION WAVE DRIVING APPARATUS AND IMAGE PICKUP APPARATUS
Simplified Explanation
The patent application describes a vibration wave driving apparatus that includes a vibration actuator and a driven member that is driven by the vibration actuator. The vibration actuator consists of a vibrator with an electric-mechanical energy conversion element and an elastic member, a pressurizing member to pressurize the vibrator, a contacting member to pressurizing-contact with the vibrator and move relative to it, and an outputting member to output a driving force to the driven member generated by the movement of the contacting member relative to the vibrator. The driven member includes an output transmission member to hold the outputting member in a direction of relative movement with a predetermined spring force.

Original Abstract Submitted
A vibration wave driving apparatus includes a vibration actuator; and a driven member configured to be driven by the vibration actuator. The vibration actuator includes a vibrator having an electric-mechanical energy conversion element and an elastic member to which the electric-mechanical energy conversion element is fixed; a pressurizing member configured to pressurize the vibrator; a contacting member configured to pressurizing-contact with the vibrator by pressurizing the vibrator by the pressurizing member and move relative to the vibrator; and an outputting member configured to output a driving force to the driven member, the driving force generated by the movement of the contacting member relative to the vibrator. The driven member includes an output transmission member configured to hold the outputting member in a direction of the relative movement with a predetermined spring force.
