A decorative cover 14 has a groove part 14a which can engage with a locking part 13d in its upper part, and has an extended part 14b for closing the opening 13c at its upper end. The cover unit is configured in such a manner that water and dust are prevented from entering the space 13b at the extended part 14b and the extended part 14b contacts with the contact part 13g in the space 13b when the decorative cover 14 is opened to complement the locking of the decorative cover 14.</p> |
