(54) Joint structure for watch and watchband


(57) To obtain a joint structure for a watch and the watch that is produced in low cost, enhanced in a design aspect and more aesthetic and free watch, and which is simple in attachment/detachment work for each joint portion to avoid a fear that a joint pin would be fallen away in case of use, the watch joint structure and the watch using the joint structure are provided in which a case joint portion (2) for joint provided in a watch case (1) and a band joint portion (4a) for joint provided in a band (4) are arranged adjacent to each other in a lateral direction, engagement holes (3), (6) and (6) in communication with each other in a lateral direction are provided in two joint portions (1) and (4a), respectively, and a joint pin (7) for coupling the watch case (1) and the band (4) is passed through the respective engagement holes (6), (3) and (6). Then, a coiled spring (8) is inserted into at least either one of the two engagement holes (3) and (6), and the joint pin (7) is inserted into an inner diameter of the coiled spring (8) so that the joint pin is retained by the inner diameter portion of the coiled spring and is applied to the two engagement holes (6), (3) and (6).
