Vibration wave motor, and driving apparatus having the same

A driving apparatus comprising:

• a vibration wave motor;
• and
• a driven member driven by the vibration wave motor,
• wherein the vibration wave motor includes:
• a vibrator including a piezoelectric element and a vibratory plate;
• a friction member configured to make a frictional contact with the vibrator;
• a pressurizer configured to press the vibrator and the friction member against each other;
• and
• a guide unit configured to guide a relative movement between the vibrator and the friction member,
• wherein the guide unit includes a plurality of rollers configured to move relative to the pressurizer, and a guide member that includes a guide portion, the guide portion being configured to extend along a relative movement direction between the vibrator and the friction member and to guide the plurality of rollers, and
• wherein the guide member includes a reinforcer configured to extend along the relative movement direction near a roller closest to a center position of a pressing force by the pressurizer.
