摘要： An optical pickup device is one in which a lens holder is held by a movable base by using a resilient wire. A restricting abutting portion is formed at a lower portion of the lens holder. When the lens holder moves excessively downward, the restricting abutting portion comes into contact with a stopper portion to restrict a downward movement of the lens holder, so that it is possible to prevent the lens holder from contacting a unit chassis. When the unit chassis is not mounted on the movable base, it is possible to prevent excessive flexing of the resilient wire caused when an opposing abutting portion of the lens holder comes into contact with the unit chassis.
