PROBLEM TO BE SOLVED: To provide a vibration type actuator of highly variable output type, capable of driving one moving body for high-power output with a plurality of vibration bodies, without the need for the holding structure for the moving body. SOLUTION: Vibration bodies 1a and 1b are arranged on both sides of a moving body 401 formed of a nearly sherical body, floatingly held on a seat 101, and pressurized for the moving body 401 by springs 102. The contact surfaces of the vibration bodies 1a and 1b, which are in pressurized contact with the moving body 401, are formed of recessed surfaces, and the moving body 401 is pressurized and held by the spring force of both springs 102. |
