ULTRASONIC WAVE MOTOR AND ULTRASONIC WAVE MOTOR-EQUIPPED DEVICE

摘要

A driving device having a vibration element, a friction member, and a pressing member for applying pressure in a direction in which the vibration element and the friction member make contact with each other, causing the vibration element and the friction member to make a relative movement by vibration generated in the vibration element. The device includes a connection member configured to transmit a driving force caused by the relative movement to a holding member of another member, wherein the holding member makes a movement caused by the transmitted driving force, and a guide member configured to guide the holding member in a moving direction when the vibration element and the friction member make the relative movement. The connection member connects the holding member to the vibration element or the friction member so as not to apply a reaction force caused by the pressing member to the holding member.
