To provide an urging apparatus capable of appropriately giving an urging force to a door.SOLUTION: In a first range, since an engaging portion 132a is not engaged with an engaged portion 122a and a first spring 140 and a second spring 150 are not elastically deformed, a form where an urging force (reactive force) is not operated (given) to a door 3. Therefore, even a weak person such as an elderly person or an infant can easily perform operation of the door 3. On the other hand, in a second range, since the first spring 140 and the second spring 150 are elastically deformed, the urging force (reactive force) can be operated (given) to the door 3 in a closing direction by using an elastic recovery force of the first spring 140 and the second spring 150. Therefore, in a door structure 1 using a gravity hinge 5, keeping the door 3 at an opening position can be suppressed.SELECTED DRAWING: Figure 2
【課題】扉に付勢力を適切に付与できる付勢装置を提供すること。【解決手段】第１範囲では、被係合部１２２ａに係合部１３２ａが係合されず、第１ばね１４０及び第２ばね１５０が弾性変形されないので、付勢力（反力）が扉３に作用（付与）されない形態を形成できる。よって、高齢者や幼児などの力の弱い者であっても扉３の操作を容易に行うことができる。一方、第２範囲では、第１ばね１４０及び第２ばね１５０が弾性変形されるので、第１ばね１４０及び第２ばね１５０の弾性回復力を利用して、扉３に閉方向への付勢力（反力）を作用（付与）させることができる。よって、グレビティヒンジ５を使用した扉構造１において、扉３が開位置に維持されることを抑制できる。【選択図】図２
