Abstract
A vibration-type actuator is downsized and stably holds the position of a vibrating body. In the vibrating body, it is possible to excite vibrations in a first bending vibration mode with two nodal lines that do not cross each other but cross short sides of an elastic body, and no nodal line that connects two long sides of the elastic body together, and a second bending vibration mode in which amplitude peaks of vibration in an out-of-plane direction of a flat-shaped plane of the elastic body lie in six respective areas formed by dividing the flat-shaped plane, and in the adjoining areas, vibrations at the amplitude peaks are in opposite phases. Combined vibrations in the first and second bending vibration modes cause an oval motion of the projecting portion, moving the vibrating body and a driven body relatively to each other in a lateral direction of the elastic body.
