PROBLEM TO BE SOLVED: To provide an adjustable door hinge which has a higher strength of each leaf of the hinge, a higher retaining force and fewer parts, a thinner overall thickness, compactness and a fitting position adjuster in right to left direction and back and forth direction. SOLUTION: Top and bottom portions of each leaf of the hinge are bent at right angle to L-shape at the top and bottom, and a projected rib is attached to the plane portion between L-bend portions in top-bottom direction. Slit holes are provided at two top and bottom positions of a base metal fittings, L-bend portions of the leaves are fitted to slits and both the leaves are overlapped each other in a state where the surface of the base metal fittings comes into contact with the tip of the rib; and the leaves and the base metal fittings are fitted in such a manner that the leaves can perform only seesaw motions relative to the base metal fittings. In addition, a surface in parallel to the door surface, which has female screw portions for back and forth adjustment, is provided at the depth side of the leaf of the hinge, a surface in parallel to the door surface having a U-shaped groove is provided also to the depth side of the base metal fittings, a groove at the head portion of the back and forth adjusting screw is fitted to the U-shaped groove, and a male screw portion for back and forth adjustment is screwed to a female threaded portion for back and forth adjustment of the leaf.
