It is characterized by comprising a bead.

With this configuration, when a diagonally downward force is applied to the lid plate, the diagonally downward force is received by the tension applied in the direction in which the upwardly inclined bead extends and the compressive force applied in the direction in which the downwardly inclined bead extends. The upwardly inclined bead and downwardly inclined bead have greater rigidity against tensile force and compressive force than against bending moment. Therefore, the upwardly inclined bead and the downwardly inclined bead can suppress deformation of the inner arm when a diagonally downward force is applied to the cover plate, thereby increasing the rigidity with which the cover device is attached to the vehicle body.

In the lid device of the present invention, the inner arm includes a reinforcing portion attached to the inside of the lid plate, an extending portion extending from the reinforcing portion toward the outside of the lid plate, and a hinge arm from the extending portion. a folded plate portion including the tip bent towards the rotating shaft and rotatably connected to the rotating shaft; and may intersect at a connecting portion between the extending portion and the folded plate portion.
