A main beam is operatively connected to the cutter head drive unit and extends rearward therefrom. A gripper body is supported by a rear end portion of the main beam to be slidable in an axial direction thereof and is provided with a main gripper to be movable along an radial direction of the main beam. A first thrust jack is mounted to be fitted between the main gripper and the main beam for advancing the cutter head and the cutter head drive unit. A shield shell is disposed so as to surround the cutter head drive unit. A second thrust jack is disposed in the shield shell, and a front gripper is mounted to the shield shell to be movable out of and into the shield shell.
