When a door is attached to a frame by using the conventional hinge, if the door is slightly displaced upward with respect to the frame, it abuts above the door frame, and conversely, the door is attached to the frame. If it shifts slightly downward with respect to the body, it may abut on the floor or below the door frame. In this way, if the door is displaced vertically with respect to the frame, it is necessary to remove the hinge and re-install it.When re-installing, the screw hole that was previously installed makes the re-installation cumbersome. It takes a lot of time and labor, and there is a problem in that the strength of the frame-side mounting portion is reduced. In addition, when both the base cylinder contact surfaces of the hinge piece are worn due to the opening and closing of the door, causing rattling of the door, there is a problem that the hinge mounting position must be changed or replaced.

The present invention has been made in view of the above situation, and the purpose thereof is to reattach the hinge when the door or the like is slightly displaced in the vertical direction with respect to the frame. The purpose of the present invention is to provide a hinge that can be easily adjusted in the vertical direction, and can be easily adjusted even if the vertical displacement occurs due to wear, thereby improving durability.
