摘要： In laser welding an optical part to a pickup case of an optical pickup device, outgas deposition on a lens surface can be inhibited, and positional shifting of the optical part can be reduced. The optical part has a lens surface facing in an optical axis direction and a protruding part formed, to be joined to the pickup case, at an end portion thereof in a direction perpendicular to the optical axis. A joint surface between the protruding part and the pickup case extends in a direction parallel to the optical axis, and the joint surface is fixed by a weld portion formed by laser irradiation. The joint surface is parallel to a bottom surface of the pickup case, and the height from the bottom surface is approximately equal to the height of the center of the lens surface.

摘要： An optical pickup device includes a house having three walls connected together whose horizontal cross-section is substantially U-shaped. A first wall supports one end of a shaft, a second wall facing the first wall supports the other end of the shaft and a third wall connects the first and second walls. A lubricant tray is surrounded by the three walls and the shaft. By the shaft being attached to an end side surface of the lubricant tray, the shaft can be integrally formed with the housing. A radius of curvature or an angle formed on a horizontal cross-section of the three walls is larger than a radius of curvature or an angle formed between one of the three walls and the lubricant tray.
