摘要： A vibration wave motor includes an element configured to be displaced by application of voltage, and an annular elastic body having a bottom surface coming into contact with the element and a drive surface having a groove, configured to drive a moving element by a vibration wave produced on the drive surface by displacement of the element. The element has a density of 4.2 to 6.0 × 10 3 kg/m 3 . A value of [(T/B) - W] is in a range of 0.84 to 1.94, where T represents a depth of the groove, B represents a distance from a bottom part of the groove to the bottom surface, and W represents a radial width of the elastic body.

摘要： A vibrational actuator includes an oscillator that generates vibrational energy; a mover that is rotationally driven around a first axis by the vibrational energy; an output shaft that rotates around a second axis by using a rotational force communicated from the mover; and a flange portion projecting out from the output shaft along a direction intersecting the second axis, that rotates together with the output shaft. Pressure is applied to the mover at a position between the flange portion and the oscillator. A distance from the first axis to an outer portion of the mover over an area where the mover is pressed against the flange portion is set to a value large enough to prevent the first axis and the second axis from becoming tilted relative to each other.

摘要： A vibration driven motor can be driven with high torque at high rotation, and has a simple structure to be manufactured easily. The motor comprises a stator in a cylindrical form, a rotor disposed on the end surface of the stator, a first piezoelectric electro-mechanical converting element for generating torsional vibration around the axis of the stator, a second electro-mechanical converting element for generating longitudinal vibration in the axial direction of the stator, and a pressing member for pressing the rotor on the stator with pressure, wherein the stator consists of two semi-cylindrical members and the first or second piezoelectric element is one or more plate-like members sandwiched by the semi-cylindrical members of the stator.
