められる。(Effects of the invention) In the present invention, the rear part of the soil removal screw conveyor connected to the shield body of the shield excavator is elastically supported by a movable support base via an elastic support. In other words, changes in the relative height of the rear part of the soil removal screw conveyor and the movable support are absorbed by the elasticity of the elastic support, and the rear part of the soil removal screw conveyor always has an appropriate spring biasing force. This eliminates excessive pushing up against the rear of the soil removal screw conveyor, avoids cantilevering, prevents damage, etc., and improves soil removal performance and operational reliability. Excavation efficiency is therefore also increased.
