摘要： A vibration type motor includes first and second vibrators, a friction member configured to contact the first and second vibrators, a pressure member configured to press the first and second vibrators against the friction member, and first and second guide members configured to guide a relative movement between the first and second vibrators and the friction member. The first and second vibrators are spaced in a direction different from a relative movement direction between the first and second vibrators and the friction member. The first and the second guide member are provided between the first vibrator and the second vibrator in a direction different from the relative movement direction. A pressure center of a pressure applied to the first vibrator and the second vibrator by the pressure member is located between the first guide member and the second guide member.

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.
