The operation tool is inserted through the operation hole of the lower shaft cylinder portion to rotate the screw member. Since the screw member is retained by the retaining portion, the vertical movement of the shaft pin is adjusted by the amount of change in the screwing amount of the screw member, thereby adjusting the vertical mounting position of the door.

[Problems to be solved by the device]

Since such a hinge up-and-down adjusting mechanism is operated only from the downward direction, it is not suitable for the up-down and left-right non-removable hinges.

That is, the non-detachable hinge does not need to care about up and down and left and right when installing it on a door or the like. However, if a vertical adjustment mechanism that operates only from the bottom is provided on the non-removable hinge, it is necessary to install the hinge so that the bottom always faces down, and there is a problem that workability is significantly reduced. .

Then, this invention aims at providing the hinge which has a vertical adjustment mechanism suitable for a non-detachable type.

[Means for solving the problem]

This invention was devised to achieve the above-mentioned object, and at least one shaft cylinder portion is formed on one blade plate, and at least two shaft cylinder portions sandwich the shaft cylinder portion on the other blade plate. The hinge is formed at a position, and the pair of blade plates are rotatably connected by inserting the shaft pin into these shaft cylinder portions. The feature is that screw members are respectively screwed in the screw holes provided at both ends of the shaft pin in the axial direction, and these screw members are retained in the shaft cylinder portion of the other blade plate so as not to come off. The retaining portions are formed, and the retaining portions are provided with operation holes for rotationally operating the screw member from the outside.

[Action]

According to this invention, if the vertical mounting position of the door needs to be adjusted with the pair of left and right blades fixed to the main body and the door, respectively, the operation tool can be operated from the operation hole of the upper or lower shaft cylinder portion. The screw member is inserted and rotated. Since the screw member is retained by the retaining portion, the vertical movement of the shaft pin is adjusted by the amount of change in the screwing amount of the screw member, thereby adjusting the vertical mounting position of the door.
