Abstract
A driving device includes a vibrator; a friction member; a first guide portion that guides the vibrator or the friction member in a first direction when the vibrator vibrates so that the vibrator and the friction member move relative to each other, the first guide portion enabling rotation of the vibrator and the friction member around an axis in the first direction; a moving member that moves when the vibrator and the friction member move relative to each other, the moving member being connected to the member to be driven; and a second guide portion that guides the member to be driven in a second direction when the moving member moves. The moving member is connected to the member to be driven such that the moving member is rotatable and movable in a direction orthogonal to the first direction with respect to the member to be driven.
