Abstract
A driving device includes a plurality of vibrating bodies including transmitting sections configured to transmit vibration to a driven section and a control section configured to change vibration tracks of the transmitting sections of at least a pair of the vibrating bodies independently from one another. When a direction in which the driven section and the vibrating bodies are arranged is represented as a first direction and a direction orthogonal to the first direction is represented as a second direction, at least the two vibrating bodies have a plurality of vibration modes in which amplitudes in at least one of the first direction and the second direction of the transmitting sections are different, and the control section drives the at least two vibrating bodies in any one vibration mode among the plurality of vibration modes.
