摘要:
A vibration driven motor has a rail-like stator secured to a bottom plate and a vibration member for generating a travelling vibration wave in an elastic member to which an electro-mechanical energy conversion element is fixed due to an application of AC electric field to the electro-mechanical energy conversion element so as to bring a portion of the elastic member into press-contact with the rail-like stator. In the vibration driven motor a surface area of the bottom portion of the rail-like stator which comes in contact with the bottom plate is less than the a surface area of the top portion of the rail-like stator.
