Hereinafter, for convenience of description, it is assumed that the fixing bracket 1300 is coupled to the door frame and the rotation bracket 1500 is coupled to the door leaf, so that the hinge device 1000 is coupled to the door frame and the door leaf to open and close the door frame. It goes without saying that the hinge device 1000 may be applied not to a door leaf having such a large size, but to a small electronic device such as opening a lid of a small home appliance or opening and closing a notebook computer.

The fixing bracket 1300 is, for example, fixed to a door frame that is a fixed support, and a fixing plate 1330 that is fixed to a door frame that is a fixed support, and a hinge shaft extending from the fixing plate 1330 to support the hinge shaft 1700 . It consists of a fixing member (1350).

In this position, when the user applies an external force and rotates the rotation bracket 1500 counterclockwise as shown in FIG. 4B, the shaft projection 1703 and the stop groove 1537 are engaged, and when further rotation is performed, the first elastic deformable member (1535) and the second elastically deformable member (1555) must be pressed by the user so as to exceed the pressing force so that the shaft projection (1703) and the stop groove (1537) are engaged. That is, it is possible to stably stop and hold the rotation bracket 1500 at a horizontal position that is a set angle and a position that divides 360 degrees into eight equal parts (since the hinge axis is an octagonal polygon). Of course, the present embodiment does not rotate 360 degrees, but may rotate 360 degrees if necessary.

In the above description, the case in which the elastically deformable member is applied to the rotating bracket has been described, but it goes without saying that the elastically deformable member may be provided on the fixed bracket or both of the rotating bracket and the fixed bracket.
