PROBLEM TO BE SOLVED: To mitigate force necessary for an opening operation of a door body at a closed position, while reliably energizing and holding the door body at the closed position and an open position.SOLUTION: The following elements are provided for constituting an energizing mechanism C of a door body 2: a main spring material 27 for swinging and energizing the door body 2 toward an open position side, provided between a first spring receiving part 21 on a first pivotal connection part 6A side of a swinging link 6 and the first spring receiving part 21 of either of fitting members 3, 4; and an auxiliary spring material 35 for swinging and energizing the door body 2 toward the closed position and the open position with elastic force smaller than the main spring material 27, provided between a third spring receiving part 23 of either of the fitting members 3, 4 and a fourth spring receiving part 24 on a second pivotal connection part 6B side of the swinging link 6, with a central position of swinging as a neutral position of energization. An energizing shaft core of the main spring material 27 passing through the first spring receiving part 21 and the second spring receiving part 22 is set at a position that stays inside of a pivotal connection shaft core X1 of the first pivotal connection part 6A, when at the closed position.SELECTED DRAWING: Figure 2
【課題】扉体を閉止位置及び開放位置で確実に付勢保持しながらも、閉止位置にある扉体の開き操作力の軽減化を図る。【解決手段】扉体２の付勢機構Ｃを構成するに、揺動リンク６の第１枢支連結部６Ａ側の第１バネ受け部２１と両取付け部材３，４のうちの一つの第１バネ受け部２１とに亘って、扉体２を開放位置側に揺動付勢する主バネ材２７が設けられ、両取付け部材３，４のうちの一つの第３バネ受け部２３と揺動リンク６の第２枢支連結部６Ｂ側の第４バネ受け部２４とに亘って、揺動中間位置を付勢中立位置として主バネ材２７よりも小なる弾性力で扉体２を閉止位置及び開放位置に揺動付勢する補助バネ材３５が設けられ、第１バネ受け部２１と第２バネ受け部２２とを通る主バネ材２７の付勢軸芯は、閉止位置において第１枢支連結部６Ａの枢支連結軸芯Ｘ１を越えない位置に設定されている。【選択図】図２
