Drive Apparatus

Provided is a self-propelled drive apparatus that enables stable drive and low cost, the apparatus includes: a movable member which has an electromechanical transducer whose one end is fixed to the movable member and the other end is fixed to a drive friction member, which is movably supported by the movable member movably in the first direction, which represents a extension-contraction direction A-B of the electromechanical transducer, where the movable member is supported movably in the first direction; a pair of plate springs which extend in a belt shape in the first direction and sandwich the drive friction member; a base member holding the plate springs in a cantilever manner in the direction of the short sides of the plate springs; and auxiliary springs disposed on the outside of the plate springs to apply elastic force only to both ends of each of the plate springs.
