A structure to prevent a drawer from falling off may include a rail and a stopping unit. The rail has an elongated side board, one side of the rail is extending to form a bottom board with an equal length as the side board. The bottom board has at least one through connecting opening. The stopping unit has a head portion, and one end of head portion has two pressing pieces, and a space formed between the two pressing pieces. When the pressing pieces move towards the space, the head portion is elastically deformed and plugged into the connecting opening of the rail. The stopping unit is configured to prevent the drawer from falling off if excessive force is applied thereon.
