If the front end is locked to the side edge of the roof shingle while being housed in the gap, the locked portion is hidden from the outside and is safe, and the appearance is good and the appearance is not spoiled.

The operation procedure for releasing the lock from the state shown in FIG. 3 (the state in which the roof panel is closed and locked) and opening the roof panel upward to shift to the state shown in FIG. 2 (the state in which the roof panel is opened) is as follows. First, the lock bar inside the side edge of the shingle on both sides is rotated downward and dropped, and then the top end of the shingle is pulled upward and both lock bars slide in each insertion hole. Then, the U-shaped locking bent portion at the tip moves upward from the insertion hole, and if the pulling of the roof plate is continued further, the locking bent portion moves backward through the cavity in the lock box and retreats. However, at the time of retreat, the tip of the free end piece of the locking bent portion is in sliding contact with the lower surface of the lip edge of the lock box, so that the tip of the lock bar does not come off from inside the lock box by engagement with the lip edge. When the locking bent portion passes over the locking hole due to the inertia of sliding, since the free end piece 3b 'of the bent portion is hook-shaped, the bent portion and the lip edge at the rear end of the lock box are closed. It stops by being hooked, and at the same time stops the backward rotation of the shingle. When the hand is released from the shingle, the locking bend slides slightly forward along the lower wall of the lock box due to the weight of the shingle, and its head moves to the center of the lower wall of the lock box (the locking hole). 2. The front end edge of the front end of the front end portion) is engaged with the engagement bent portion into the engagement hole, and the engagement is returned to the state shown in FIG.
