PURPOSE: A door structure for an electrical fence is provided to open/close the door of an electrical fence with least force since the principles of a tension spring and a pulley are properly utilized. CONSTITUTION: A door structure for an electrical fence comprises a first space and a second space. The first space is formed between one of insulating support rods(8) and a neighboring insulating support rod. The second space is formed between the first space and the neighboring insulating support rod. A handle body(7) is formed in the second space. An elastic member(2), a pulley(1) and a wire(9), of which at least part returns the pulley, are successively coupled. The elastic member is restored from one insulating support rod to the other insulating support rod in the first space. One end of the wire is fixed to the other insulating support rod and the other end of the wire is coupled to the handle body.
