The first case segment 2a is provided with a ridge portion 3 projecting toward the second case segment 2b. The second case segment 2b is provided with a groove portion 4 in which the ridge portion 3 is fitted. The first case segment 2a and the second case segment 2b are provided with outer end faces 5a, 5b perpendicular to a side face 30 of the ridge portion 3 and opposite to each other in positions adjacent to the ridge portion 3 on a case-external side.
