PROBLEM TO BE SOLVED: To provide a lighting device which inhibits the occurrence of defects, such as deformation (warpage etc.) and creaking sounds, even when thermal expansion amounts of an LED attachment base and a cover differ from each other.SOLUTION: In a lighting device 100, end caps 50b are installed in a frame 40 and end parts. An end cover 60b is attached to each end cap 50b so as to slide in a longitudinal direction of the frame 40. A cap protrusion 58b having a right-angled triangle cross section shape is formed at each end cap 50b. An end cover installation hole 68b into which the cap protrusion 58b may enter is formed at each end cover 60b. When the cap protrusion 58b enters the end cover installation hole 68b, a clearance formed in the longitudinal direction of the frame 40 is formed between the cap protrusion 58b and the end cover installation hole 68b. |
