The present invention provides a knee joint protection band during walking, which is a field belonging to a sewing product or a healthy walking assistance product manufacturing technology. Various conventional products which have been developed and distributed consider a knee portion as important such that the products are made up to a portion for holding the knee. Accordingly, if a user wears the products, a protection band is frequently separated from the knee during walking such that there is inconvenience that a user has to release and fasten the protection band again many times. The conventional product is frequently deviated from the position of the knee because of bending and spreading motion of the knee during walking such that the product has to be continuously rearranged. Accordingly, the conventional product has been difficult to be completely worn. The present invention provides the protection band, which prevents movement and separation of a wearing position after being worn by moving together with the knee portion spread as a reverse function. As a completely different thinking from a fixed idea, the protection band of the present invention narrows a rear side of the knee by considering that the rear side of the knee is always folded, and binds a front side of the knee with separated band units by considering that the front side of the knee is spread, such that the protection band is able to be worn without being fell down from the knee, thereby alleviating efforts of a wearer to be preferred by the wearer and to increase revenue.본 발명의 보행보호밴드는 이미 다양한 제품이 개발되어 유통되고 있으나 그 발명품이 모두 무릎부위를 중시하여 무릎을 수용하는 부위까지 만들어져 있어서 착용을 하면 보행으로 보호대위치가 무릎에서부터 이탈되어 자주 다시 풀어 묶거나 또는 풀어버리므로 인하여 본 제품의 개발은 계속 수정되어지는 사유로 기술개발이 필요로 하는 봉제제품이거나 건강보행보조분야의 제조기술에 속하는 분야이다,본 발명은 이미 시중에서 다양하게 개발되고 있고 많은 개발품이 있지만 무릎은 보행을 할 때 굽고 펴는 운동으로 인하여 위치가 자주 벗어나 계속 수정해 주어야 하는 부위에 속하므로 지금까지 완전한 착용이 어려웠던 제품이기도 하다,이러한 어려운 부위이기에 과제의 해결수단은 착용 후 위치가 이동되지 않고 이탈되지 않도록 하는 기법을 개발하는 과제인데 이러한 어려움은 역기능으로 벌려지는 무릎부위에
