Abstract
A vibration-type actuator includes a vibrator, a contact member, a ball, and a base table having a third guide. The vibrator has an elastic member and an energy conversion element. The contact member is fixed to the base table, contacts the elastic member, and extends in a predetermined direction. The vibrator and the contact member are driven along the predetermined direction due to a vibration generated by a voltage applied to the energy conversion element. A first guide provided on the contact member extends in the predetermined direction and a second guide that is connected with the vibrator faces the first guide and moves integrally with the vibrator. The ball is held between the first guide and the second guide rollably in the predetermined direction. The second guide extends in the predetermined direction and includes a fitting projection portion loosely fitted to a groove portion provided on the third guide.
