SOLUTION: The cover device 25 comprises an attachment 26 to be detachably mounted on one of ends of the opening 15 and a cover body 27 for opening/closing the opening 15. The cover body 27 is coupled with the attachment 26 via a flexible portion 34 which is deformable in the opening/closing direction A and swings in the direction A with the flexible portion 34 as the center. The flexible portion 34 is formed to be thinner than the attachment 26 and the cover body 27, and the attachment 26, the cover body 27 and the flexible portion 34 are integrally molded of a plastic resin. |
