摘要： PROBLEM TO BE SOLVED: To simply form a straight line part and a curved part by connecting a coil on a straight rigid rod material, and continuously coating the rigid rod material and the coil with a flexible tube. SOLUTION: A plurality of straight rigid rod materials 1 comprising a stainless steel pipe and aluminum are connected through a coil 2, and the rigid rod material 1 and the coil 2 is continuously coated with a flexible tube 3 such as vinyl chloride. A core metal 4 is interposed in the connection part of the rigid rod material 1 and the coil 2, the large diameter part 4a of the core metal 4 is inserted in the rigid rod material 1, the small diameter part 4b of the core metal 4 is inserted in the coil 2, and the core metal 4 is fixed on the rigid rod material 1 by screwing a screw 5 penetrating the rigid rod material 1 in the large diameter part 4a of the core metal 4. When a handrail comprising a straight line part and a curved part is executed, a part incorporating the coil 2 is flexed to be curved, and supported on an open bracket so as to maintain the curved state.
