PROBLEM TO BE SOLVED: To apply no load to a hinge so as to smoothen its action in fastening a door toward a fixed frame body by forming a first pivot hole in a fixed blade board into an oblong hole, boring a pressing guide hole reaching the first pivot hole from the end face of the fixed blade board, and inserting a pressing element, a coil spring elastically pressing the element and a pressing bolt into the pressing guide hole. SOLUTION: A hinge A is constructed of a fixed blade board 10, a rotational blade board 20 and a pivot 30, which can be moved orthogonally. In the position abutting to the pivot 30, a pressing element 15 is arranged freely slidably in the axial direction of a pressing element guide hole 14, and a pressing bolt 17 presses the pressing element 15 to the pivot 30 because of resilient spring force of a coil spring 16 so as to press it to the side closer to the tip of a first gudgeon 11. In this way, the pivot is not affected because it can be moved when a door is squeezingly fastened to the fixed frame body over the whole circumference, so that the door can be fastened completely. If the pulling fastening force is released, a return to the former state is carried out immediately.
