The present invention realizes a locking device preferably using the space formed between a fixed rail and a moving rail. The present invention achieves a compact configuration by preventing unnecessary parts from protruding or being exposed to the outside of the space formed between the fixed rail and the moving rail; and minimizes the strength decrease of the fixed rail and the moving rail by preventing relatively unnecessary holes from being formed on the fixed rail and the moving rail. |
