The present invention is related to a floor hinge applied with a rack gear driving method. Durability is remarkably improved in comparison with a cam method, and precision operation is secured even if the floor hinge is used for a long time since a piston operation method by a pinion gear part coupled to a rotary shaft of a door and a rack gear part of a piston is applied to the floor hinge. The floor hinge can be applied to a structure with a bidirectionally opened door. |
