<P>PROBLEM TO BE SOLVED: To provide a segment joint structure capable of achieving miniaturization and weight reduction of both a male side joint member and a female side joint member and reducing manufacturing cost. <P>SOLUTION: In a segment joint structure for joining segments 1, 1 to each other, a male side fitting part 13 is formed in such a shape as to have a trapezoidal cross section by inclining one or both of upper and lower outside surface parts 14, 14 so as to decrease in thickness as proceeding in the segment sliding direction, and a fitting groove 24 is provided in which upper and lower inside surface parts 23, 23 facing each other are inclined so as to come close to each other as proceeding in the segment sliding direction, such that the male side fitting part 13 is fitted into a female side fitting part 22. A plurality of lock teeth 15, 15..., 25, 25... for regulating movement of both male and female side joint members 3, 5 by mutually engaging respectively are provided on the outside surface parts 14, 14 of the male side fitting part 13 and on the inside surface parts 23, 23 of the fitting groove 24. <P>COPYRIGHT: (C)2013,JPO&INPIT |
