PROBLEM TO BE SOLVED: To simplify construction work.SOLUTION: A fixture body 1 is moved in such a manner that head parts 123A of bolts 123 protruding from each of the connection plates 12 come right above first insertion grooves 413 of a supporting member 4. Then, the head parts 123A of the two bolts 123 are inserted into the first insertion grooves 413 respectively when the fixture body 1 is lowered, and furthermore, a cylindrical part 123C of each bolt 123 is inserted into a second insertion groove 414 by passing through the first insertion groove 413. That is, by the two bolts 123 fixed at the fixture body 1 being locked at the peripheral edges of the two second insertion grooves 414 provided at a pair of fitting parts 412 of th supporting member 4 separately, the fixture body 1 is suspended and supported at the supporting member 4. Thus, the fixture body 1 can be supported by the supporting member 4 just by inserting the bolts 123 from the first insertion grooves 413 to the second insertion grooves 414, construction work for installing the lighting fixture to the ceiling can be simplified. |
