Abstract:
A vibrating type actuator which hardly causes a failure and can suppress occurrence of abnormal noise while not preventing vibration from being excited in a vibrator. The vibrating type actuator comprises a vibrator in which vibration is excited, and a contact body which is in contact with the vibrator, wherein the vibrator and the contact body move relatively to each other. The vibrating type actuator comprises a holding member which holds the vibrator, a pressurizing member which pressurizes the vibrator against the contact body, a support member which movably supports the holding member in a pressurizing direction, in which the pressurizing member performs pressurization, and an vibration damping member which is in contact with the holding member at a plurality of portions while sandwiching the holding member in a direction orthogonal to the pressurizing direction.
