PROBLEM TO BE SOLVED: To reduce the manufacturing cost of a luminaire by installing a hook piece for good workability, on a mounting member of the luminaire to restrict the upward movement of the luminaire. SOLUTION: A mounting member 34 :fixed to a chassis 32 are placed on an upper placement part 6 of a T bar 3 to support a luminaire main body 35. A hook 64 of a hook piece 61 mounted to the mounting member 34 is locked from down side to a middle lock part 7 of the T bar 3, thereby restricting the upward movement of the luminaire 35. The hook piece 61 is formed by a single elastically deformable metal plate and is provided with a pair of first lock parts 66 on the lower aide and a second lock part 67 on the upper side. The first lock parts 66 are hooked on a first lock reception part 56 on the lower side of the mounting member 34. The second lock part. 67 is pushed into a second lock reception part 59, forming a rectangular hole for locking.
