Abstract
A vibration-type driving apparatus is capable of, in a case where a sintered body is impregnated with resin, preventing the resin that has hardened from interfering with other members. A movable body is brought into pressure contact with a vibrating body having an electro-mechanical energy conversion element and an elastic body. The vibrating body and the movable body are moved relatively to each other through vibrations excited in the vibrating body. The movable body has a frictional surface including the sintered body impregnated with the resin and comes into contact with the vibrating body. The movable body has a sloped surface adjacent to the frictional surface in a cross section perpendicular to a direction in which the vibrating body and the movable body move relatively to each other. An angle formed by the frictional surface and the sloped surface is greater than 90 degrees and less than 180 degrees.
