Thus, the first coil holder, the second coil holder, and the third coil holder can be arranged in a stacked manner in the Z direction without causing rattling.

Abstract: In the actuator, the viscoelastic members are arranged at positions at which the support body and the movable body face each other in the first direction, and the magnetic drive circuit drives the movable body in the second direction which crosses the first direction. The viscoelastic members connect the movable body and the support body together while having the thickness direction thereof in the first direction and extending in the second direction. Therefore, resonance caused when the movable body is vibrated can be restricted. Reproducibility of vibration acceleration corresponding to the input signals can be improved by utilizing the spring elements of the viscoelastic members in the shearing direction, thus enabling the actuator to vibrate with delicate nuances. Further, the viscoelastic members can be prevented from being pressed in the thickness direction and greatly deformed, therefore, preventing the gap between the movable body and the support body from greatly varying.

The first yoke includes a first connecting plate part and a second connecting plate part that extend toward the second yoke. Thus, welding of the first connecting plate part and the second yoke and the second connecting plate part and the second yoke can be efficiently performed on a different side in the first direction (a side where the second yoke is located).

The second viscoelastic member interposed between the movable body and the second end plate part in the first direction properly contacts with the movable body and the second end plate part.
