学式ピツクアツプ装置。[Claims for Utility Model Registration] An optical system that guides light emitted from a semiconductor laser to a recording medium and guides the light transmitted or reflected by the recording medium to a light receiving element, and a lens disposed within the optical system. An optical pickup device comprising: a lens holder that holds a lens holder; a housing member that houses the lens holder; and a pressing member that presses the lens holder housed in a housing part of the housing member toward the housing part, The lens holder and the accommodating portion are in contact with each other at at least two places, and the resistance force at both the contact points acts on the lens holder at a predetermined angle with respect to the direction of the pressing force by the pressing member. An optical pickup device characterized in that a contact means is provided on the lens holder or the housing member.
