摘要

PROBLEM TO BE SOLVED: To provide a vibration type driving device that prevents a driving device Of a vibration type motor, made of driven members press-contacted with a plurality of vibrators, from causing deterioration in driving efficiency and decrease in speed even if individual differences occur between the vibrators.SOLUTION: The vibration type driving device has: a first vibrator that comprises electric-mechanical energy conversion elements and is configured to be press-contacted with a driven body; a second vibrator that comprises electric-mechanical energy conversion elements and is configured to be press-contacted with the driven body; and a first electric element connected in series to the second vibrator. The first vibrator is connected to a drive circuit, the second vibrator and the first electric element are connected in parallel to the first vibrator, and the second vibrator is connected to the drive circuit through the first electric element, where when a resonance frequency of the first vibrator is f1 and a resonance frequency of the second vibrator is f2, f1f2 is satisfied.
