PURPOSE: To improve strength of a coupling part by inserting a foil between a sleeve end part and a tube to circularly enclose the tube and be relatively movable to the tube, and fixing and coupling a sleeve center part to the tube.
CONSTITUTION: In a binding and coupling part of a carbon tube or a graphite tube provided with a sleeve 4 surrounding a binding position and composed of fibers, the sleeve 4 is formed of plural parts 5, 6, 6', and foils 7, 7' are inserted between end parts 6, 6' of the sleeve 4 and tubes 1, 1' to circularly enclose the tubes 1, l', and be relatively movable to the tubes 1, 1' A center part 5 of the sleeve 4 is fixed to the tubes 1, 1'. The foils 7, 7' relatively movable to tube outer surfaces form parts to weaken attachment between the sleeve 4 and the tubes 1, 1', thereby rapid stress increase is not formed at the end parts 6, 6' of the sleeve 4.
