ABSTRACT:
A pressure force adjusting mechanism for a vibration wave driven motor for applying a predetermined pressure force for frictionally driving an annular elastic member in which a travelling vibration wave is formed relative to a movable member is provided with a fixed support member for supporting the elastic member so as to have a degree of freedom in the axial direction thereof, a pressing member for pressing the elastic member from the axial rear thereof toward the movable member, and a holding member receiving the reaction force of the pressing member and fixedly fitted to the fixed support member. The holding member and the fixed support member are fixed by a projected portion which is formed on the holding member being engaged with the bayonet type engagement portion of the fixed support member. The engagement portion has its pressure force holding engagement surface against which the projected portion bears formed into an inclined surface inclined with respect to the axial direction.
