PROBLEM TO BE SOLVED: To reduce darkness generating between two adjacent covers.SOLUTION: A mounting member 21 is formed in a long manner, and a substrate 221 is mounted on it. A cover is formed by a translucent material in a long manner, and mounted on the mounting member 21 so as to cover the substrate 221. The cover is mounted on the mounting member 21 in a state where the same direction as the longitudinal direction of the mounting member 21 is made to be a longitudinal direction and the same direction as the width direction of the mounting member 21 is made to be a width direction. Also, in the cover, dimension in the longitudinal direction is longer than the mounting member 21, and both sides in the longitudinal direction protrude further outward than the mounting member 21 in a state of being mounted on the mounting member 21. |
