To provide fittings that can miniaturize a frame body and a face material and that are equipped with a hinge capable of being concealed when closed.

In a hinge 10 for supporting a door 3 in a door frame 2, a first link 40 is rotatably supported on a frame-side case 20, and a second link 50 is pivotally supported on the other end side of the first link 40, which achieves minimization of a face dimension of the frame-side case 20. The other end side of a third link 60 is slidably supported in a guiding groove 37 of a door-side case 30, which achieves minimization of a depth dimension of the door-side case 30. This achieves minimization of each of a face dimension of a jamb 4 and a depth dimension of the door 3 and enables efficient miniaturization of the door frame 2 and the door 3.
