To fix a circuit board without forming a fixing hole therein.SOLUTION: A board fixing structure includes a circular circuit board, a pair of fixing rings with fixing thread grooves formed on the outer edges, and a housing in which the inner circumferential surface is cylindrical, and the inner circumferential surface is formed with a fixing side screw groove that is screwed into the fixing screw grooves, and one fixing ring is positioned at a desired height within an accommodation space by screwing the fixing thread groove of one fixing ring into the fixing side thread groove, the circuit board is placed on one of the fixing rings, and the vicinity of the outer periphery on both sides of the circuit board is sandwiched between the pair of fixing rings by screwing the fixing thread groove of the other fixing ring into the fixing side thread groove.SELECTED DRAWING: Figure 1 【課題】回路基板に固定穴を形成することなく固定する。【解決手段】円形な回路基板と、外縁に固定用ネジ溝が形成された一対の固定用リングと、内周面が円筒状であり、固定用ネジ溝に螺合する固定側ネジ溝が内周面に形成された筐体とを備え、一方の固定用リングの固定用ネジ溝を前記固定側ネジ溝に螺合させることにより一方の固定用リングを収容空間内の所望高さに位置設定し、回路基板を一方の固定用リングの上に載置し、他方の固定用リングの固定用ネジ溝を固定側ネジ溝に螺合させることにより回路基板の両面における外周近傍を一対の固定用リングで挟み込む。【選択図】図１
