PROBLEM TO BE SOLVED: To provide a joint structure for a tube body that is inexpensive and has superior design.SOLUTION: A joint structure for a tube body that joins a first tube body 23 and a second tube body 25 together such that an end of the second tube body 25 abuts on an intermediate part of the first tube body 23 from the outside of its radial direction includes a bracket 31 which has one end side fastened to a wall surface of the first tube body 23, and the end of the second tube body 25 is fitted and fixed to the other end side of the bracket 31 fastened to the side of the first tube body 23. With the joint structure, thermal strain generated when the first tube body 23 and second tube body 25 are joined by welding is not generated, so subsequent strain removal processing is unnecessary, operability of joining operation is improved to make joining costs lower, and a tube body joint body as a product, for example, a handrail is improved in shape-related precision and reliability. |
