プ用アクチュエータ。In an actuator for an optical pickup, a moving axis is provided at the center of a cylindrical magnet, and the moving axis is moved in the axial direction and/or rotated around the axis. a cylindrical focus yoke having a gap around its outer periphery; and a cylindrical focus yoke fixed perpendicularly to the axial direction of the moving shaft, with one end attached to a fixed support member on the substrate via an elastic member. and a cylindrical focus coil fixed coaxially with the axis with a gap provided between the gaps, a focus lens provided offset to one side from the center of the axis, and the focus yoke at a position offset to the other side from the center of the axis. It is composed of a holding member having an axial tracking coil provided close to it, and a tracking yoke with a magnet that is fixedly provided on the substrate and is close to the tracking coil and applies a magnetic field perpendicular to the coil.
