Zusammenfassung:PROBLEM TO BE SOLVED: To provide a lighting device having a hanging part which is robust over stress.SOLUTION: A lighting device 1000 has a hanging part 900 fixed to an attached part. The hanging part 900 includes: a pipe 920; an attachment flange 930 having a cylindrical part 940 covering an end part of the pipe 920; and an assembly mechanism which loosely attaches the pipe 920 to the cylindrical part 940. The assembly mechanism attaches the pipe 920 to the cylindrical part 940 in a displaceable manner so as to ease stress applied to the lighting device.SELECTED DRAWING: Figure 45 【課題】照明装置において、応力に強い吊部を有する照明装置を提供する。【解決手段】被取付部に固定される吊部900を有する照明装置1000において、前記吊部900は、パイプ920と、前記パイプ920の端部を覆う円筒部940を有する取付フランジ930と前記円筒部940に対して前記パイプ920を緩く取付けた組立機構とを備えた。前記組立機構は、照明装置に加えられた応力を緩和するように、前記パイプ920を前記円筒部940に対して変位可能に取り付けている。【選択図】図45
