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.

摘要： A vibration wave motor includes a vibrator, a friction member having a sliding surface, a guide member, a flexible substrate, and a fixing member configured to fix the friction member, the guide member, and the flexible substrate. The vibrator and the friction member move relative to each other in a predetermined direction. The fixing member includes a substrate-fixing portion configured to fix the flexible substrate, which includes a joint portion, an extending portion extending along the predetermined direction, a bent portion configured to reverse and turn back the extending portion, and a fixed portion to be fixed to the substrate-fixing portion. The flexible substrate is fixed on a surface of the substrate-fixing portion provided in a direction opposite to a direction in which the vibrator is brought into pressure-contact with the friction member.
