ABSTRACT:
An optical pickup device includes a hosing 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.
