Patent attributes
A slide rail includes a fixed-side rail, a movable-side rail, and a reinforcing structure that prevents detachment of the movable-side rail from the fixed-side rail. The reinforcing structure includes a fixed-side engaging portion attached to the fixed-side rail, and a movable-side engaging portion attached to the movable-side rail. The fixed-side and the movable-side engaging portions are configured, while allowing sliding of the movable-side rail, to come in contact with each other due to an action by a large load in a detaching direction input between the fixed-side rail and the movable-side rail, and to be engaged with each other to restrict movement of the movable-side rail in the detaching direction. A contact surface, that comes in contact with the movable-side engaging portion, of the fixed-side engaging portion includes surface regions that have mutually different positions in the detaching direction and are provided side by side in a sliding direction.
