Summary:PROBLEM TO BE SOLVED: To improve traveling stability of an optical pickup by keeping a sufficiently large spring load added to an engaging position to suppress variation in spring load applied to the engaging position even when a spring body having a small elastic pressing force and hardly causing characteristic deterioration is used. SOLUTION: The optical pickup feeding device is provided with a lead screw 2 and a resin tooth body 6. The tooth body 6 is attached to an optical pickup A to extend in an cantilever state in a direction orthogonal to the lead screw 2. The tooth body 6 is elastically pressed from the back by a spring body 7. The pressing position (axial position L) of the tooth body 6 with respect to an engaging position (a) between the engaging tooth 62 of the tooth body 6 and the lead screw 2 by the spring body 7 is offset more to the free end side 63 of the tooth body 6 than the engaging position a. An offset width H is set larger than the inclination angle adjust width of a guide shaft 2. COPYRIGHT: (C)2009,JPO&INPIT
