Zusammenfassung:	PROBLEM TO BE SOLVED: To precisely adjust the tilt angle of an objective lens with inexpensive structure. SOLUTION: The optical pickup has a capsule 21 composed of a pair of a bottomed cylindrical capsule half bodies 21A, 21B. The capsule 21 with an adjusting spring 17 is formed by inserting the adjusting spring 17 into respective capsule half bodies 21A, 21B. The height of the capsule 21 is freely extended and contracted against the adjusting spring 17. The capsule 21 is inserted between a pressing part 20A of an optical base 1 and a receiving part 2A of an act base 2 against the adjusting spring 17 to adjust the tilt angle by the adjusting spring 17 and both tilt angle adjusting bolts 13, and the act base 2 is fixed to the optical base 1 by adhesive UV. Thereafter, the capsule 21 is pulled out against the adjusting spring 17, thereby removing the capsule 21 from between the pressing part 20A and the receiving part 2A. COPYRIGHT: (C)2007,JPO&INPIT
