Abstract
A vibration-type driving apparatus includes a vibrator holder, wherein a plurality of vibrators each having at least an electro-mechanical energy conversion element and an elastic member having a contact portion formed therein are connected to a vibrator holding member, for generating an ellipsoidal movement of the contact portion, to move, relative to the vibrator, a driving member contacting the contact portion. The plurality of vibrators are connected to a surface of the holding member at a side at which the contact portion contacts the driving member, and on a surface of the vibrator holding member opposite to the side at which the contact portion contacts the driving member, a pressing member is placed to set the contact portion to be pressed and contacted to the driving member.
