To provide a hinge structure for the door of a gate, in which the execution of works is saved, which has excellent workability and in which a height place is also adjusted finely.

A door-side upper hinge 21 is disposed under a column-side upper hinge 11 and a door-side lower hinge 22 onto a column-side lower hinge 12, and connected by upper and lower shafts 31, 32. The upper shaft 31 is driven to the door-side upper hinge 21 in the column-side upper hinge 11 and the lower shaft 32 is screwed to a screw-worked internal surface in the column-side lower hinge 12 at that time, and the door-side lower hinge 22 is supported pivotally.
