Abstract
A first weight portion of a vibration actuator includes an inner-side enlarged portion that protrudes from an end portion of a solid head in a direction of a vibration axis and that is inserted into an opening portion extending within a first compression coil spring along the direction of the vibration axis. An outer peripheral surface of the inner-side enlarged portion becomes continuously smaller in diameter from a base end towards a free end, with the vibration axis being the center of the diameter. That is, the inner-side enlarged portion has the shape of a truncated cone. The inner-side enlarged portion is inserted into the opening portion of the first compression coil spring and the opening portion is utilized to change the length of the inner-side enlarged portion in the direction of the vibration axis, thereby changing the mass of the first weight portion.
