ABSTRACT:
A supporting device supports a vibrating body or contacting member at one or plural locations in a vibration wave driven motor in which the aforesaid vibrating body is caused to generate traveling waves when an alternating current is applied to the electromechanical energy transducing element connected to the vibrating body thereby to move relatively the aforesaid vibrating body and the contacting member being in contact therewith under pressure. This supporting device is provided with a first supporting member which extends in the direction substantially perpendicular to the traveling direction of the traveling vibration wave, one end of which is coupled to the aforesaid vibrating body or contacting member, and a second supporting member which extends in the traveling direction of the traveling vibration wave, one end of which is coupled to the other end of the aforesaid first supporting member and the other end of which is connected to a fixing portion, thus making it possible to support the vibration wave driven motor reliably without any loss of vibrating energy.
