To provide a door hinge structure capable of enlarging an angle width in which an assisting action for automatically opening/closing a door is exerted, and capable of satisfactorily exhibiting a closing action after full closing and an opening action after full opening without enlarging the thickness dimension of a cam member.SOLUTION: When a door is fully closed or when the door is fully opened, upper and lower ends of an inclined part 65 of a second cam part 36 are made coincident with upper and lower ends of an inclined part 54 of a first cam part 34. A stepped part is formed at a boundary between the inclined part 54 of the first cam part 34 and a recessed part 55, and a stepped part is formed at a boundary between the inclined part 65 of the second cam part 36 and a recessed part 66. In the fully closed state and the fully opened state of the door, opposing gaps D are formed, which results from the stepped parts, between a projection part 53 of the first cam part 34 and the recessed part 66 of the second cam part 36, and between the recessed part 55 of the first cam part 34 and a projection part 64 of the second cam part 36.SELECTED DRAWING: Figure 8
【課題】扉が自動的に開閉される助勢作用が発揮される角度幅を大きくすることができ、しかも、カム部材の厚み寸法を大きくすることなく、全閉後の閉じ作用や全開後の開き作用が良好に発揮される扉ヒンジ構造を提供する。【解決手段】扉を全閉状態としたとき、或いは扉を全開状態としたときの第２カム部３６の傾斜部６５の上下端部と、第１カム部３４の傾斜部５４の上下端部とを一致させる。第１カム部３４の傾斜部５４と凹部５５との境界部に段差部を形成し、第２カム部３６の傾斜部６５と凹部６６との境界部に段差部を形成し、扉の全閉状態及び全開状態において、第１カム部３４の凸部５３と第２カム部３６の凹部６６との間、及び第１カム部３４の凹部５５と第２カム部３６の凸部６４との間に、段差部に由来する対向間隙Ｄを形成する。【選択図】図８
