A rotary type vibration wave driving apparatus which is capable of reducing local wear of a contacting member and of reducing performance deterioration due to long term operation is provided. The apparatus includes a electro-mechanical energy conversion element, an vibration member fixed to the electro-mechanical energy conversion element and vibrated by a voltage being supplied to the electro-mechanical energy conversion element, and a moving member being brought into contact with the vibration member and frictionally driven by the vibration, and is configured such that the moving member includes a supporting portion extended from the main body portion of the moving member, and a contacting portion extended from the supporting portion and being brought into contact with the vibration member, and such that each of the supporting portion and the contacting portion is configured to be elastically deformable in the rotation axis direction of the moving member.
