支持機構。[Claims for Utility Model Registration] A reference shaft, a support shaft disposed parallel to the reference shaft, and at least an objective lens attached thereto, supported between the shafts so as to be movable in the axial direction of the reference shaft. At least the optical block of the optical pickup device is attached to one side of the optical block with its rotation axis inclined at a predetermined angle relative to the moving direction of the optical block, and the reference shaft is held between the circumferential surfaces of a pair of rollers. two sets of positioning rollers that are brought into contact with each other so as to be in contact with each other; and an elastic displacement member that is attached to the other side of the optical block opposite to the side on which the positioning rollers are attached and that is elastically displaced in a direction substantially perpendicular to the axial direction of the support shaft. a roller support member having a roller support member, and a roller support member that is attached to the roller support member with rotational axes inclined at a predetermined angle relative to the moving direction of the optical block, so that the support shaft is sandwiched between the circumferential surfaces of the pair of rollers. A support mechanism for an optical pickup device, comprising a pair of preload rollers brought into contact with an optical pickup device.
