PROBLEM TO BE SOLVED: To improve a locking device for a panel structure so that it has good operability by avoiding erroneous insertion of the locking metal fitting of the locking device that uses a frame of a C-cross section which has the advantage of being able to store electrical wiring therein, and that also uses the locking metal fitting. SOLUTION: A series of overhangs 11, which are opposed to a receiving surface 5 which is the upper surface of a frame 2 of a C-cross section open at the center of the upper surface, and which form a guiding part 10 permitting passage of the flange 14 of a locking metal fitting 3 between it and the back of the receiving surface 5, are formed in positions close to the back of the receiving surface 5. An insertion error preventing structure 16 obstructing passage of each flange 14 of the locking metal fitting 3 through a position other than the guiding part 10 is provided at the open longitudinal end face of the frame 2. |
