The present invention relates to a brace backrest fixing device. Since an accurate dimension can be maintained without a welding operation, assembling properties can be improved. Also, nuts and bolts, when being disassembled, can be easily separated. When a metal composed of a lightweight material and bent in a polygonal shape is combined with a net wrapped over the metal, a cable tie is used. A brace is hung on an upper end ring of a frame, and a waist band is assembled with the lower end of a backrest by a bolt and a nut. After an engine is combined to a frame, and a cable tie is used corresponding to multiple holes. Then, assembling properties can be improved. During disassembly, separation can be easily performed. The entire quality of a brace backrest can be improved. In addition, a decoration which stimulates acupuncture point is attached to the backrest to be helpful for health.
