[Prior art]

 Conventionally, in order to rotatably attach a door to a door frame or the like, a hinge made up of two blade plates rotatably held by a shaft through a tube portion is provided with a blade whose tube portion is located below. The plate was fixed to the door frame, and the other blade was fixed to the door with screws. However, the door frame to which the door is attached is constructed in the field, and most of the doors are off-the-shelf products. The current situation is to perform some rework.

According to the conventional mounting method, when the door is not properly mounted on the door frame or the like, the blade plate is removed from either the door or the door frame so that the door is properly mounted. The blades were reattached again after changing the position. This not only complicates the work, but also causes the door or door frame to have a screw hole in the front so that the vane plate cannot be attached again.

In order to solve this problem, various adjustment hinges having a function of adjusting the mounting position of the door have been proposed. For example, there is Japanese Utility Model Laid-Open No. 62-16672. According to this proposal, one of the vanes is attached to the seat plate, and the clearance between the seat plate and the vane plate is adjusted by adjusting the amount of screwing of the adjusting screw member to adjust the left and right of the door, and to adjust the vertical bearing part. The upper and lower parts of the door are adjusted by moving the shaft pin up and down and the other vane plate up and down with the screws attached to the upper and lower ends.
