<p><P>PROBLEM TO BE SOLVED: To join a pipe and a coating layer with ease. <P>SOLUTION: A handrail is constituted to cover a wire 2 and a synthetic resin coating layer 3 on the outer periphery of a metal pipe 1 and form an anti-slip recess/projection pattern B on the surface of the coating layer 3 by partial protrusion due to the wire 2. The handrail fits the wire 2 on the outer peripheral face 1a of the pipe 1, and integrally laminates the wire 2 and the coating layer 3 on the outer peripheral face 1a of the pipe 1 by extrusion-molding the coating layer 3. Thereby the wire 2 and the coating layer 3 are brought into close contact with the outer peripheral face 1a of the pipe 1 not to allow positional shift. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
