Abstract
A vibrating actuator includes a contact body and a vibrating body that vibrates, has an energy conversion element, and has an elastic body in contact with the contact body to move relative to each other from the vibration. The contact body has a base part, a thin plate part, a support part, and a friction member. The thin plate part extends from the base part toward an annular center axis of the base part and the support part is disposed at an end of the thin plate part. The friction member is disposed to the support part as a member separate from the support part and in contact with the elastic body. Density of the friction member is higher than density of the thin plate part. A weight ratio of the thin plate part to a total weight of the friction member and the support part is 0.5 to 1.5.
