Objective lens driving apparatus, optical pickup

An objective lens driving apparatus configured to be provided in an optical pickup together with a semiconductor laser and an electro-optic component, the objective lens driving apparatus comprising:

• an objective lens holder including an objective lens, a focusing coil for driving the objective lens holder in a focusing direction, and a tracking coil for driving the objective lens holder in a driving direction;
• a fixed part;
• a plurality of elastic support members, each including a first end and a second end, and configured for elastically supporting the objective lens holder from the fixed part, and
• holding members mounted on the objective lens holder, each of the holding members being configured for holding the plurality of elastic support members,
• wherein the respective first ends of the plurality of elastic support members are held by the holding members and fixed at respective fixing positions to the objective lens holder by the holding members,
• wherein the respective second ends of the plurality of elastic support members are fixed to the fixed part, and,
• wherein each of the holding members is joined together with the objective lens holder by fitting together first and second pairs each comprised of a concavity and a convexity, the pairs being spaced from one another in the focusing direction, each pair of one of the concavities and one of the convexities having together first mating faces shaped so as to position the fixing positions of the elastic support members in the length direction thereof and second mating faces shaped so as to position the fixing positions of the elastic support members in the focusing direction.
