An optical wiring unit includes a tray, an operating member supported by the tray and that moves in a front-rear direction of the optical wiring unit as a reference to a neutral position, a slide piece including a latch, and one or more springs that bias the operating member toward the neutral position. The slide piece slides with respect to the operating member between a restriction position and a release position. A protrusion amount of the slide piece from the operating member at the release position is smaller than a protrusion amount of the slide piece from the operating member at the restriction position. The slide piece is disposed at the restriction position when the operating member is at the neutral position and slides toward the release position when the operating member moves in the front-rear direction from the neutral position.

Optical wiring unit and optical termination box

An optical wiring unit includes: a tray that includes a bottom plate; and a lid body that includes a top plate facing the bottom plate in an up-down direction. An accommodating space that accommodates an optical fiber is formed between the bottom plate and the top plate. one of the tray and the lid body includes: an outer wall portion; and an inner wall portion inside the accommodating space with respect to the outer wall portion. The other of the tray and the lid body includes an intermediate wall portion inserted between the outer wall portion and the inner wall portion. The inner wall portion has a dimension in the up-down direction smaller than that of the outer wall portion.
