PROBLEM TO BE SOLVED: To provide a hinge that enables a pair of hinge-connected fitting blades to be opened/closed without much resistance and an opened state of the fitting blades to be retained stably by setting a position of the three points appropriately.SOLUTION: A hinge includes: a fitting blade 3 having a pressurizer receiving part 7, a pressurizer 8, and a spring 9 that energizes the pressurizer in a direction; a cam 10 fitted externally on a pivot shaft 6, the cam having first to third planes 10a to 10c, curved surfaces 10d, 10e connecting the two adjacent planes, and an engaging recess 10f on an outer periphery; and a fitting blade 2 having a stopper claw 11 engaged with the engaging recess 10f for stopping rotation of the cam 10. The pressurizer 8 is pressed against an outer periphery of the cam 10 by force of the spring 9, and the pressurizer 8 comes in contact with the first to the third planes 10a to 10c respectively when an opening angle between the fitting blades 2, 3 is 0°, 90°, and 180°.SELECTED DRAWING: Figure 2
【課題】ヒンジ結合された対の取付け用羽根板の開閉操作を大きな抵抗を受けずに行えるようにし、なおかつ、その取付け用羽根板の開き状態も３箇所の設定位置で安定して保持される蝶番を提供することを課題としている。【解決手段】取付け用羽根板３が、圧子受け入れ部７と、圧子８と、その圧子を一方向に付勢するばね９を具備し、ピボット軸６に外嵌されるカム１０は、第１〜第３の平面１０ａ〜１０ｃと、隣り合う２つの平面間を繋ぐ曲面１０ｄ、１０ｅと、係合凹部１０ｆを外周に有し、取付け用羽根板２は、前記係合凹部１０ｆに係止してカム１０を回り止めするストッパ爪１１を備え、ばね９の力で圧子８がカム１０の外周に押し当てられ、取付け用羽根板２，３の開き角が０°の位置、９０°の位置１８０°の位置で圧子８が第１〜第３の平面１０ａ〜１０ｃにそれぞれ面接触する蝶番にした。【選択図】図２
