PURPOSE:To fix a wire receiver to a nodal ring under an extremely stable condition by providing a deformed part having a shape corresponding to each other, on the inside circumferential surface of the nodal ring in a curved tube for an endoscope, and a joint part of a wire receiving member, and widening a weld area. CONSTITUTION:When fixing each wire receiver 18, wach wire receiver 18 is joined to a fixing position of each wire receiver 18 in its circumferential direction, on an inside circumferential surface 20b of a body 20a. Thereafter, laser light is irradiated to a joint part of the wire receiver 18 and the inside circumferential surface 20b, and its joint part is welded, by which each wire receiver 18 can be fixed as one body through a weld part 21 to a fixing position to the inside circumferential surface 20b of a nodal ring 20. Also, the weld part 21 by laser light is fixed by the weld part 21 of two places in both the front and rear ends of the wire receiver 18. |
