摘要 A device for supporting an objective lens of an optical pickup in which one end of a first leaf spring is secured to a spring mounting portion of a base through a first elastic member. A connective member is secured to the other end of the first leaf spring through a second elastic member. One end of a second leaf spring is secured to the connective member through a third elastic member.
