摘要： The invention provides an optical disc device conducting highly accurate skew adjustment, avoiding an increase in the number of components, and achieving downsizing. This optical disc device includes: a guide shaft for supporting an optical pickup and guiding its movement; a chassis the guide shaft is attached to; a coil spring attached to the chassis for applying force to an end of the guide shaft; an adjustment screw for adjusting the force applied by the coil spring, provided opposite the coil spring with respect to the guide shaft; and a weight addition member attached to the chassis, wherein internal threads for engaging with the adjustment screw are formed in the weight addition member, and the axis of the adjustment screw engaged with the internal thread, the center of a cross section of the guide shaft perpendicular to its axis, and the axis of the coil spring are aligned along the same line.
