<p>PROBLEM TO BE SOLVED: To facilitate execution of a hand rail and contrive stability support by supporting a cylindrical hand rail support ring by integrally fixing it with the screw seat of a wall face and fitting the hand rail in a fitting hole, and making a stopper for preventing penetration of the hand rail to the fitting hole. SOLUTION: The fitting hole 41 of a hand rail support ring 4 is made by reducing diameter size from each opening to the center part and making it slender toward the interior, and a stopper 42 is disposed in the inner periphery of the fitting hole 41. At the time, a diameter minimum part 43 is formed in the center part of the axial direction of the fitting hole 41. The diameter size of the interior narrowness of the hand rail support ring 4 is matched to the diameter size of a hand rail T, which does not penetrate the fitting hole 41, and each diameter size of the diameter minimum part 43 and a hole opening part are set. At the time of execution of the hand rail T, penetration for the fitting hole of the hand rail T is prevented, a mounting state is stabilized, and hand rail execution is facilitated at a site. Even if unevenness occurs on the diameter size of the hand rail T, unevenness is absorbed by the stopper 42. Thereby the support state of the hand rail T by a support bracket 1 can be stabilized.</p> |
