ABSTRACT:
An objective lens driving apparatus for an optical pick-up, in which an objective lens is loaded on a driving body which is driven in a horizontal and a vertical direction and an objective lens driving portion is supported by four elastic linear members, includes two supports having two penetration holes each through which two pairs of elastic linear members pass, wherein the objective lens driving body is connected to the two pairs of elastic linear members, so as to prevent the driving body from rolling.
