Abstract

PURPOSE:To prevent wear in use, by assembling a sliding member for the sliding part, in a lens barrel. CONSTITUTION:In a lens consisting of barrel 1, lens frame 5 and sliding ring 11 which are inserted, a sliding piece 12 is provided with a sliding member 15 to reduce sliding friction, and the lens frame 5 is provided with sliding member holders at three circumferential parts. A sliding member 6 suported 9 to a shaft hole 8 with a slope is fitted to pull the sliding members at both ends of the sliding member holder with a spring 10, allowing to make accurate fitting between thelens frame and the barrel with wear resistance.
