SOLUTION: A joint 1 for joining two adjacent segments 15, 15 together comprises a male type joint member 2 which is provided on a longitudinal joint surface 17 and a female type joint member 7 which is provided on the other joint surface 19 and is fit to the male type joint member 2. The male type joint member 2 includes a fitting member 3 which has plural grooves 6 formed on the surfaces thereof, and the female type joint member 7 includes a pair of fitted members 8, 8 which has plural grooves 12 on the surfaces thereof to be engaged with the grooves 6 of the fitting member 3. By fitting the fitting member 3 between the pair of fitted members 8, 8 so as to engage the grooves 12 of the pair of fitted members 8, 8 with the grooves 6 of the fitting member 3, the two adjacent segments 15, 15 may be joined together.
