PROBLEM TO BE SOLVED: To provide a root wrapping component, a root wrapping block and root wrapping in which the time required for the work of mounting to a strut and dismounting from the strut can be shortened without using fastening means, and a manufacturing cost can be reduced with a simple configuration.SOLUTION: A root wrapping component is characterized by having a base part, a concave fitting part, a convex fitting part and a step difference part. The base part is provided with a strut insertion hole, and is radially extended from a strut insertion hole inner surface. The concave fitting part and the convex fitting part are alternately provided in the circumferential direction of the strut insertion hole. The step difference part is positioned in the concave fitting part, and is radially formed step-wise from the strut insertion hole inner surface. A root wrapping block is characterized by dividing the root wrapping component in the circumferential direction of the strut insertion hole into a fan type shape in multiple ways. Also, the root wrapping is characterized in that the paired root wrapping components are formed by irregularly fitting the concave fitting part to the convex fitting part in the circumferential direction of the strut insertion hole, and the step difference part is irregularly fitted in the radiation direction of the strut insertion hole.SELECTED DRAWING: Figure 4 |
