PROBLEM TO BE SOLVED: To maintain fine appearance of a hinge by preventing the surge of a shaft core which occurs in a hinge of such a type that the shaft core is not fixed to a shaft cylinder part. SOLUTION: In this hinge 1, the shaft core 5 connects an upper shaft cylinder part 6 of a blade plate 2 on the door side to a lower shaft cylinder part 7 of a blade plate 3 on the outer frame side, and both blade plates 2, 3 are turnable to each other through the shaft core 5. The shaft core 5 is structured to be supported in a vertically movable manner by the upper shaft cylinder part 6, and the insertion length D of the shaft core 5 into the lower shaft cylinder part 7 is set so that the lower end 25 of the shaft core 5 does not contact the internal wall of the lower shaft cylinder part 7 when the upper shaft cylinder part 6 has an inclination of 1°to the lower shaft cylinder part 7.
