发明名称 VIBRATION TYPE ACTUATOR
摘要 A vibration type actuator including a vibrator having an electro-mechanical energy conversion element and an elastic member fixed to the electro-mechanical energy conversion element; a base unit configured to fix the vibrator; a moving body configured to come into press contact with the vibrator and capable of being moved by the vibration; a press member configured to bring the vibrator and the moving body into press contact with each other and transmit a drive force of the moving body to an output unit; and a bearing unit configured to rotatably support the output unit with respect to the base unit, wherein the bearing unit is arranged on an outer peripheral side of the vibrator and the moving body in a direction orthogonal to a direction of rotation axis of the output unit.
