支持機構。In an optical pickup in which an objective lens for irradiating detection light onto a recording medium is provided so as to be able to perform correction operations in the optical axis direction of the detection light and in a direction direct to the optical axis of the detection light, the objective lens is formed on a holding member. This holding member is supported by a spring, and a coil for driving the objective lens in the optical axis direction and a direction perpendicular to the optical axis is also fixed to the holding member. An objective lens support mechanism for an optical pickup, characterized in that:
