<p>PROBLEM TO BE SOLVED: To provide a vibration actuator which has a simplified structure, is easily assembled, and whose downsizing, such as reduction of a diameter of a housing, is easily promoted.SOLUTION: A vibration actuator 1 has one coil 3, a portion of a housing 2 corresponding to a vibration region P of magnets 4 is formed at least by a magnetic material, and a shaft 20 fixed to the housing 2 is formed of a non-magnetic material. Weight parts 6, 7 have bearing parts 25, 26 which slide against the shaft 20, and are provided for both sides of the magnets 4 in a vibration axis line direction L. Elastic members 30, 31 are provided for both sides of the weight parts 6, 7 in the vibration axis line direction L, and one end of each member is inserted into recess parts 27, 28 for receiving spring which are formed for the weight parts 6, 7.</p> |
