PROBLEM TO BE SOLVED: To provide a lighting apparatus having a structure in which the number of component elements of a latch type fixture for fixing a front cover to a main body of the apparatus and the number of assembly steps can be reduced.SOLUTION: A latch-type fixture 5 is constructed as a structure comprising bearing pieces 54, 54 integrally formed with packing depressing fittings 26, 27; an engaging claw 51d that can be engaged with an engaging piece 56 arranged at a main body 1 of the apparatus; a hook 51 supported at the bearing pieces 54, 54 through a supporting shaft 53 and rotatable between an engaging position where the engaging claw 51d is engaged with the engaging piece 56 and a releasing position where the engaging claw 51d is released from the engaging piece 56; one leaf spring 55 for biasing the hook 51 against the engaging position side, thereby the number of component parts and the number of assembly steps are reduced. In addition, the leaf spring 55 is made as a structure in which it is fixed individually separate from the supporting shaft 53 rotatably supporting the hook 51, thereby their assembly work is facilitated..SELECTED DRAWING: Figure 11
【課題】前面カバーを器具本体に固定するラッチ式固定具の部品点数及び組立工数を少なくすることが可能な構造の照明器具を提供する。【解決手段】ラッチ式固定具5を、パッキン押え金具26,27に一体形成された軸受片54,54、器具本体1に設けられた係止片56に係合可能な係止爪51dを有するとともに、軸受片54,54に支持軸53を介して支持され、係止爪51dが係止片56に係合する係合位置と係止爪51dが係止片56から外れる解除位置とに回転可能な掛け金51、及び、掛け金51を係合位置側に付勢する1つの板ばね55とを備えた構造とすることで、部品点数及び組立工数を少なくする。また、板ばね55は、掛け金51を回転可能に支持する支持軸53とは個別に取り付ける構造とすることにより、組立作業を簡単にする。【選択図】図11
