A vibration member for use in a vibration wave driving apparatus, and a vibration
wave driving apparatus, the vibration member including an elastic member having
a through hole, a fastening member having a threaded portion, an electro-mechanical
energy transducer having a through hole, and a shaft inserted into the through
holes of the elastic member and the electro-mechanical energy transducer, the shaft
having a threaded screw portion that meshes with the threaded portion of the fastening
member, and a step that restricts a position of the elastic member relative to
the shaft in a thrust direction, wherein the elastic member is sandwiched between
the step of the shaft and the fastening member and fixed therebetween by screwing
and fastening the threaded screw portion of the shaft with the threaded portion
of the fastening member, and the shaft is restricted from rotating relative to
the elastic member.
