Abstract:
A sliding member structure is stably operated by preventing rattling and achieves a decrease in cost. A male helicoid is provided in a fixed barrel, and a female helicoid is provided in a focus barrel. The focus barrel is made of a light-transmissive resin. The fixed barrel is made of a sliding material to which a curable material is not fixed. The fixed barrel and the focus barrel are set by a fixture to dispose the male helicoid and the female helicoid with a predetermined clearance, and the curable material is filled into the clearance between the male helicoid and the female helicoid. The curable material is cured by irradiating UV rays. A cured material layer is formed on a surface of the male helicoid.
