Abstract
A vibration type motor has a vibrator; a frictional member, a pressurization unit that causes the vibrator and the frictional member to come into pressure-contact with each other, a retaining member that retains the frictional member, and a fixing unit that fixes the friction member to the retaining member, and the vibrator and the frictional member make relative movement by the vibrator being vibrated. The frictional member has a first area including an area that contacts the vibrator and a second area including an area that is retained by the retaining member. A size of the first area in an orthogonal direction that is orthogonal to both the direction of the relative movement and a pressure direction of the pressurization unit is smaller than a size of the second area in the orthogonal direction.
