<p>PROBLEM TO BE SOLVED: To provide a joint for a handrail bar, by which connection works are simplified at a low cost and correction works are made unnecessary. SOLUTION: The joint for the handrail bar is constituted in such a manner that a working surface 2 formed in a projecting curved surface shape such as a spherical surface and a round bar-shaped inserting section 3 continuously connected to the working surface 2 are formed integrally at one bar end of the handrail bar 1, and fitted into a center hole 6 formed at the central section of a receiving surface 5 at the bar end of another handrail bar 4 and the working surface 2 of the handrail bar 4 is brought into surface-contact and bonded with the receiving surface 5 of another handrail bar 4.</p> |
