<p>A tension rod has: a flat constricted section which is formed by compressing the intermediate part of a material rod consisting of fiber-reinforced plastic; and rod body sections which are the portions of the material rod which remain on both sides of the constricted section. A stopper has stopper-forming parts which grip the constricted section. A socket has a socket body section and an engagement section which is provided at an end of the socket body section. The socket is provided with a rod pass-through hole which continuously penetrates through both the socket body section and the engagement section and through which the tension rod is passed. The stopper is adapted to be capable of engaging with the engagement section while being inserted through the insertion hole section of the rod pass-through hole.</p> |
