The present invention relates to a driving apparatus arranged to perform driving control of a travelling member, such as a shutter member, by using a vibration wave motor. According to the present invention, the travelling member is arranged to be driven by the spring force of a spring member. The travelling member is held in a stopped state against the spring force by the stopping torque of the vibration wave motor, and by causing the vibration wave motor to generate a standing wave, the stopping torque is cancelled so that the travelling member starts travelling by the spring force.
