摘要： To provide an optical pickup device adapted such that for adhesion fixing of a holder for holding an LD or a light-receiving element to an optical pickup casing via an ultraviolet-curable adhesive, curing shrinkage during ultraviolet irradiation can be reduced and adhesion fixing achieved with high positioning accuracy. In a structure for adhesion fixing of a holder for holding an LD or a light-receiving element to an optical pickup casing via an ultraviolet-curable adhesive, since protrusions are provided at peripheral sections (UV irradiation light source side) on a bonding surface of the holder, a section exposed to strong UV light is first cured, then after the adhesive has moved from an uncured section, the amount of shrinkage of the first cured section in a Z-direction is reduced, and the uncured section is cured.

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.
