Abstract
Provided is a vibration wave motor including: a vibrator; a friction member that comes into frictional contact with the vibrator; a press member that pressurizes the vibrator and the friction member into frictional contact with each other; a first guide member and a second guide member that guide the vibrator and the friction member so as to allow relative movement of the vibrator and the friction member; a hold member that holds the friction member and the first guide member; and a fixing member. The friction member and the first guide member are fixed to the hold member with the fixing member.
