An objective lens actuator 25, for driving an objective lens 1 for focusing lights upon a recoding surface of an optical disc, comprises a moving part 2, which comprises the objective lens 1 and a coil; a magnet, which is fixed on a yoke and drives the moving part 2; a plural number of elastic support parts, each of which supports the moving part 2 at an end thereof; a first fixing portion 5a and a second fixing portion 5b, which fix other ends of the plural number of elastic support parts 4 and are disposed opposite to each other in a focus direction; and a moving mechanism 6, which is provided on the first and second fixing portion 5a and 5b, so that the first and second fixing portions 5a and 5b can move in the focus direction, relatively, and thereby providing the objective lens actuator 25 enabling to reduce the dynamic relative tilt between the optical disc and the objective lens 1 (i.e., reducing the tilt of the objective lens 1 in the tangential direction when operating), as well as, an optical pickup and an optical disc drive.
