PROBLEM TO BE SOLVED: To provide a handcart brake wire protection structure capable of preventing a brake wire from being worn and broken due to an inside exposure of a steel plate coil caused by bending overly of a wire tube.SOLUTION: A handcart brake wire protection structure 1A includes a non-elastic wire sleeve 20 which has a bend part 34 and has an inner peripheral surface of being smooth cylindrical shape. An opening end 21a of a frame pipe side of the wire sleeve 20 is inserted to a frame pipe 3. An opening end 22 of a brake grip part side of the wire sleeve 20 is connected to a brake grip part 16. Further, a brake wire 12 is inserted to the wire sleeve 20 in between the frame pipe 3 and the brake grip part 16.
