Abstract
A fixing body includes a coil holding part that is disposed to surround a magnet externally in a radial direction and holds the coil disposed outside the bobbin-shaped coil holding part in the radial direction. The coil holding part includes a coil protection wall portion that is disposed inside the coil in the radial direction of the coil with a gap being interposed between the coil protection wall portion and the magnet, and inhibits contact between the coil and the movable body. Elastic supporting parts are a plurality of leaf springs installed between the fixing body and the movable body to sandwich the movable body in the vibration direction, and support the movable body such that, in a non-vibration state and in a vibration state of the movable body, the movable body is freely movable in the vibration direction without making contact with the coil holding part.
