An adjustment/holding section (21) for adjusting the inclination of a guiding shaft (22) relative to a base (1) is fixed to the base by a first support point (1n), a second support point (23), and a third support point (24), and the guiding shaft (22) guides an optical pickup (2) in a radial direction. When the optical pickup (2) is at a first position on the inner circumferential side of the optical disk, a bearing section (2c) of the optical pickup (2) is located on a line connecting the first support point and the second support point. When the optical pickup (2) is at a second position on the outer circumferential side of the optical disk, the bearing section (2c) of the optical pickup (2) is located on a line connecting the first support point and the third support point. |
