摘要： A vibration wave motor includes a vibrating plate having a rectangular surface; a piezoelectric device bonded to the vibrating plate, and configured to vibrate at high frequency; and a projection provided on the vibrating plate or the piezoelectric device. In the vibration wave motor, a natural vibration mode, which has a resonant frequency equal to or adjacent to a resonant frequency of torsional vibration in a natural vibration mode under a state in which the vibrating plate, the piezoelectric device, and the projection are integrated, is a natural vibration mode of bending vibration in a direction parallel to or orthogonal to a torsion center axis of the torsional vibration in the natural vibration mode. The projection is provided at a position closer to an antinode than to a node, which are in the direction orthogonal to the torsion center axis of the torsional vibration in the natural vibration mode.

摘要： In a linear driving apparatus including a vibration wave motor, a sliding guide method is used as a guiding method for a moving member. The apparatus further includes a driving target body movable in a moving direction, a transmission member configured to engage with the driving target body, abut against the abutment part of the moving member, and transmit the driving force of the vibration wave motor to the driving target body, and a biasing member configured to apply a biasing force between the transmission member and the abutment part. The direction of a frictional contact force that the vibrator receives from the friction member and the direction of a biasing contact force that the abutment part receives from the biasing member are parallel and opposite, and the load center of the distribution load of the biasing contact force exists in the range of the outside shape of the vibrator.
