The present invention relates to a knot member for a wood material for a net wall bar comprising: horizontal grooves which allow horizontal lines, arranged in the horizontal direction, to be inserted therein; and vertical grooves which are formed in the direction perpendicular to the direction of the horizontal grooves, are located on front sides or back sides of the horizontal grooves, and allow vertical lines, arranged in the vertical direction, to be inserted therein; and knot members made of a wood material. The knot members are joined on intersections where the horizontal lines and the vertical lines, which constitute the net wall bar made of ropes for rehabilitation treatment or play of children, are crossed by each other. Therefore, the horizontal lines and the vertical lines do not move easily. In addition, costs for manufacturing the knot members can be reduced as the knot members are made of a wood material. Accordingly, the knot member has excellent economic efficiency. |
