<p>Provided is a slide rail mechanism including a movable rail that is difficult to deform even if an external force acts on the movable rail and that is stably kept in a state in which a portion of the movable rail is inserted into an inner space of a lower rail. Of an upper rail 20, an inner portion 22 inserted into an inner space IS of a hollow-shaped lower rail 40 includes a region having a closed cross-section in a slidable movement direction of the upper rail 20, a normal direction of the closed cross-section being the slidable movement direction.</p> |
