摘要： The distal end of a flange of a stator serving as a contact member is located on the outer peripheral side of one linear portion of an elastic member serving as a vibration member, and the inner peripheral side of this linear portion of the elastic member is located on the proximal side of the flange. The ratio of the response amplitude of the flange of the stator to the amplitude of the elastic member is kept almost constant in all areas of contact portions between the two members.

摘要： A planar auxiliary supporting member for supporting an elastic member for generating a vibration is arranged. The elastic member contacts a rail-shaped stationary member, and moves along the stationary member. The rigidity of the supporting member is set to be low, so that the elastic member as a stator stably moves along the stationary member.

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.

摘要： A vibration wave driven motor having a vibratory elastic member provided with an electro-mechanical energy conversion element, and a rail-type stator on which the elastic vibratory member is resiliently pressed by, for example, springs. When A.C. power is supplied to the electro-mechanical energy conversion element, a traveling vibration wave is generated in the elastic vibratory member so that a frictional force is produced to act between the stator and the elastic member so as to cause a relative movement between the elastic vibratory member and the stator. At least one of the sliding surface of the elastic vibratory member and the sliding surface of the stator has a smoothly curved configuration, so as to improve the durability of the motor.

摘要： First and second guide means are provided to both a movable member which moves together with a vibration member, which is in press contact with a rail-shaped stator, and the rail-shaped stator. The first and second guide means have different functions: the first guide means restricts the degree of freedom of the movable member, and the second guide means receives a total compression counterforce of the vibration member.

摘要： In a vibration wave driven motor, an elastic body of an elliptic shape is provided where different degrees of stiffness or rigidity are available with the arcuate portions and the straight portions, and the ratio between the distortion energy and the vibration energy that part in the generation of the natural frequency for the A vibration mode is arranged virtually equal to that ratio for the B vibration mode, thus enabling the matching of frequencies for both A and B modes.
