Preferably, the bearing hole 22 can adjust the distance between the wall and the rotation axis. As shown in FIG. 2, a long groove 26 is provided in a direction perpendicular to the bracket 12 on the upper surface of the bearing member 20, and is fixed such as a bolt 28 along the longitudinal direction of the long groove 26. The gap is adjusted by fitting the member into the rim groove of the bearing hole 22. The bolt 28 is interposed with a washer 29 for firm fixing.

On the other hand, the bearing member 20 is rotatably coupled to the bracket 12 by the hinge coupling means (30). Preferably, it is coupled to rotate 360 ° about an imaginary axis orthogonal to the upper rotation axis A of the door. Therefore, since the bracket 12 does not necessarily need to be fixed horizontally or vertically with the bearing member 20, the bracket 12 can be installed freely without regard to a wall of a thin thickness or a pattern of a door frame.

Specifically, the hinge coupling means 30 has a locking hole 32 formed in the bearing member 20 and a hinge catching shaft 34 formed in the bracket 12.

The locking hole 32 is formed in the bearing member 20 in a direction parallel to the bearing hole 22 from the end thereof. That is, the locking hole 22 is opened downward, and is dug into a semicircular shape so that the locking hole 22 can be fitted to the hinge locking shaft 34 when engaged.
