Abstract
In a vibration motor in which an electro-mechanical energy conversion element which is periodically deformed is joined to an elastic member to constitute a vibration member, a travelling vibration wave is generated in the vibration member, and the vibration member and a contact member which is urged against the vibration member are relatively moved by the vibration wave, a plurality of contact portions are formed on a portion of the elastic member on a driving side at predetermined intervals, and when the contact portions are engaged with the contact member, the relative movement between the vibration member and contact member is caused by the vibration wave.
