When making a curve in the vertical direction, the direction was mainly changed by operating the upper and lower shield jacks.

た。Problems to be Solved by the Invention However, in the Japanese Patent Publication Publication No. 59-18513, turning in the left and right direction became accurate and easy, but when turning in the vertical direction, operating the shield jack was troublesome. However, in this structure, the radius of curvature becomes large, and it becomes necessary to excavate the upper or lower part of the face, creating a large gap between the ground and the shield, which may induce ground subsidence. The structure of 59-16639 is such that it can move accurately and easily in all directions, left, right, up and down, but its structure is complicated and manufacturing is not simple, and it requires a large amount of force during excavation work. This was a problem because it sometimes lacked robustness during operation.
