Claims

[Scope of utility model registration request]

an objective lens for irradiating a recording surface of a recording medium with spot light; the objective lens is movable in the optical axis direction of the objective lens and in a direction perpendicular to the optical axis direction; The support mechanism includes a support mechanism that supports the objective lens substantially perpendicularly to the recording surface, and a driving force applying means that applies a driving force to the objective lens, and the support mechanism includes a base member and a cantilever-shaped member attached to the base member. a first flexible member that is attached to the optical axis and is flexible in either one of the optical axis direction and a direction perpendicular thereto; and a first flexible member that is coupled to the free end of the first flexible member via a relay member. a cantilever-shaped second member that is flexible in a direction other than the one of the optical axis direction and a direction perpendicular thereto and that holds the objective lens at a free end;
a flexible member, each end of the first and second flexible members is fitted into a mounting groove formed in the relay member and coupled with an adhesive, and the relay member has a An optical information recording/reproducing device, characterized in that a guide portion for guiding each end of the first and second flexible members into the mounting groove is protruded near the mounting groove. Pickup device.
