1. A vibration wave driving apparatus comprising:
a vibration actuator; and
a driven member configured to be driven by the vibration actuator,
wherein the vibration actuator includes:
a vibrator having an electric-mechanical energy conversion element and an elastic member to which the electric-mechanical energy conversion element is fixed;
a pressing member configured to press the vibrator;
a contact member configured to press-contact the vibrator by pressing the vibrator using the pressing member and move relative to the vibrator; and
an outputting member configured to output a driving force to the driven member, the driving force generated by the moving of the contact member relative to the vibrator, and
wherein the driven member includes an output transmission member configured to hold the outputting member in a direction of the relative movement with a predetermined spring force.
