PROBLEM TO BE SOLVED: To provide a light fitting which enables its posture to be stabilized relative to a ceiling material while inhibiting influence on lateral swing of the ceiling material.SOLUTION: A body part 31 is connected with a hanging bolt 41 hung from a ceiling slab 40 and is inserted into an embedded hole 440 provided at a ceiling material 44. A flange part 32 protrudes outward from a lower end part of an outer peripheral surface of the body part 31 over an entire periphery. Each contact part 33 is formed so as to protrude to an area above an upper surface of the flange part 32 and contact with a lower surface of the ceiling material 44. Further, the contact part 33 is formed so that a friction force acting between the contact part 33 and the ceiling material 44 is reduced compared to a case where the upper surface of the flange part 32 is placed in contact with the lower surface of the ceiling material 44.SELECTED DRAWING: Figure 1
【課題】 天井材の横揺れに対する影響を抑えながらも、天井材に対する姿勢を安定させることができる照明器具を提供する。【解決手段】 本体部３１は、天井スラブ４０から垂下された吊りボルト４１に連結され、天井材４４に設けられた埋込穴４４０に挿通される。鍔部３２は、本体部３１の外周面の下端部から全周にわたって外向きに突出する。接触部３３は、鍔部３２の上面よりも上方に突出して天井材４４の下面に接触するように構成され、鍔部３２の上面を天井材４４の下面に接触させる場合よりも天井材４４との間に作用する摩擦力が低減されるように構成されている。【選択図】図１
